Underwater acoustic tracking and two way messaging system
A system where a large number of underwater devices can transmit their precise position relative to a fixed underwater beacon, by transmitting two short duration, precisely timed acoustic tones (pings). The arrival time of the pulses at the fixed underwater transceiver beacon will relay the transmitter's precise position relative to that beacon. The two pings code for two numbers; either the range and bearing or an X, Y coordinate of each object with respect to the beacon. Data messages can be sent to and received from the beacon, used for command, control and status. The pulses can be a single frequency and have duration of around a 1 ms and operate one or many frequencies to allow multiple cycles to be overlapped in time. This coding scheme allows many devices to send the data simultaneously in the cycle for group tracking from last position or as independent cycles for unambiguous tracking. The transducers used in the system can be omni-directional hydrophones. The tracking grid size is a function of the acoustic frequency chosen and range from 1000 m for 40 KHz and 6000 m for 8 kHz. The system requires that all nodes in the system keep precise synchronized time.

Optimizations are provided for controlling an amount of radiated power (i.e. spectral flux density) that is being transmitted to a particular location. To that end, one or more antennas are used to transmit a power signal. Then, position information for each of those antennas is determined.

Thereafter, how much power is radiated to a particular location is controlled so that the power never exceeds a certain threshold value. This control is achieved by dynamically adjusting the transmit power of the antennas based on the information obtained from the position information, the environmental information, and the antenna radiation pattern information.

A monopulse antenna system can include a monopulse detector assembly (MDA) that is configured to steer a monopulse antenna based on the magnitude of an elevation ratio or azimuth ratio independently of the phase of the ratio. To prevent the direction of the monopulse antenna from being changed too frequently, the MDA can employ ratio bins to determine when the direction of the monopulse antenna should be reversed. Also, the MDA may enforce a hold period during which a change in the direction of the monopulse antenna will not be performed. The MDA can employ one or more mapping equations to generate a steering signal as a function of the magnitude of the ratio. The mapping equations can be selectively employed based on whether tracking is being performed at or near the ratio null.
A monopulse tracker includes multiple dual-axis monopulse antenna systems that are angled with respect to one another. The orientations of the monopulse antenna systems create a much larger field of view for the monopulse tracker to eliminate the need to steer the monopulse tracker. The monopulse tracker can be configured to estimate a position of an object based on tracking information received from more than one monopulse antenna system therefore increasing the accuracy of the estimated position. The multiple monopulse antenna systems can be arranged in a low-profile housing to facilitate use of the monopulse tracker on aircraft.
An angle of arrival system is configured to efficiently measure phase differences. The angle of arrival system includes a master receiver for demodulating the signal received at one antenna and for implementing a tracking loop to identify the timing of symbols within the signal. This timing information can be fed back as a synchronization signal to a despreader in the master receiver and to a despreader in each of a number of slave receivers to synchronize the timing at which each signal is despread. Because despreading is synchronized, the outputs of the despreaders can be used to directly calculate phase differences between each pair of signals. In this way, the slave receivers do not need to implement a demodulator or a tracking loop. When the received signal is a non-spread signal, the phase differences between each pair of signals can be calculated directly from the modulated samples of each pair of signals without despreading.

Mainlobe detection process for monopulse antenna systems
A mainlobe detection process can include a number of tests that are performed to define when the monopulse antenna system will transition from open loop scanning to closed loop scanning and then to tracking. A hybrid tracking technique is also provided which adaptively discovers and corrects for phase alignment error. Magnitude-only tracking can be performed initially to locate the nulls in the azimuth and elevation ratios and to identify the magnitudes of these ratios at these nulls. Phase tracking can be then performed. During phase tracking, phase corrections can be repeatedly applied to the azimuth and elevation difference channels to correct any phase error that may exist. During this process, the magnitudes of the ratios can be used to determine how the phase corrections should be adjusted. Once the hybrid tracking process is complete, the monopulse antenna system is properly phase-aligned and phase tracking will be correctly employed.

A transmit signal can be distorted with non-linear distortion, and one or more characteristics of the non-linear distortion can be periodically changed in accordance with a change key.

Embodiments are directed to systems and methods for communicating between nodes in a mobile ad hoc network. In one scenario, a node in a mobile ad hoc network communicates with another node in the network using both code division multiple access (CDMA) and frequency division duplexing. The communication is coded prior to transmission to the other node, and includes applying direct sequence spread spectrum (DSSS) modulation to a transmission signal at a specified bit rate over a specified spectrum. The DSSS coding is applied in accordance with a processing gain which spreads the spectrum relative to the bit rate of the transmission. The coded communication is then transmitted over a specified frequency band allocated to the node over which the node transmits data and over which the other node receives the data.
A transmitter or receiver can include a phased array antenna system in which multiple characteristics of a transmitted or received beam can be controlled electronically. For example, in embodiments that include a transmitter, dual outputs of N signal modifiers can be connected to orthogonal inputs of N dual-orthogonally polarized antenna elements. Each signal modifier can modify the amplitude and phase of a communications signal in two parallel signal paths to produce two signal components each of which is an amplitude-modified/phase-shifted version of the communication signal. Multiple characteristics of the combined beam can be simultaneously controlled by setting the amplitude and/or phase-shift parameter values in the dual signal paths in the signal modifiers to combined values that individually affect each of the multiple characteristics of the combined beam.

Embodiments are directed to synchronizing time among nodes in a network. In one scenario, a first node receives a timing message which provides an indication of the current time as measured by a second node at transmission of the timing message.

The first node also applies a weighting factor to the current time of the first node to adjust the current time forward or backward, and combines the determined propagation time with the adjusted clock time of the first node to generate a new, synchronized time and transmission frequency, which is broadcasted to other nodes in the network.

A fault-tolerant display system includes a dual thin film transistor -TFT- panel with pixel cells having two independently-controlled switching transistors (561, 571)); as such, primary source and gate drivers (132, 131) are operative to drive the display with first TFT transistors, while secondary source and gate drivers (122, 121) are operative to drive the display with second TFT transistors. As the display incorporates an additional TFT within the pixel cell which is driven independently, reliability is increased even at the pixel level. In this way, individual pixels of the LCD panel are driven simultaneously and independently by two pairs of source drivers and gate drivers, such that if one of the driver pairs fails due to some fault, the other driver pair can continue to drive the LCD panel without loss of information despite the failure of the first driver pair.

Efficiently detecting presence of a hidden signal using frequency domain multiplication
The presence of a hidden signal can be detected efficiently using frequency domain multiplication. A detector system can be employed to search for a hidden signal across a wide spectrum in real time. The detector system can divide multiple antenna inputs into a series of blocks and then convert these blocks to the frequency domain possibly in a parallel fashion. Corresponding blocks from each input can then be conjugate multiplied, and the results of this conjugate multiplication can then be averaged over time. If a signal is hidden in the inputs, this averaging will reduce the noise floor thereby revealing the presence of the hidden signal at a particular frequency.
Spatially combining signals may include receiving a number of RF input signals at a number of RF input connectors. At least one of the RF input signals is a variable envelope signal. A variable envelope signal is converted into two or more outphased constant envelope signals. The two or more outphased constant envelope signals are amplified. The amplified outphased constant envelope signals are radiated. At a spatial combiner aperture, the radiated amplified outphased constant envelope signals are combined to create a combined signal. The combined signal is output onto an output RF connector.

Embodiments are directed to representing radio frequency (RF) signals in a visualization using particle bursts. In one scenario, a computer system instantiates RF signal sources in a virtualization, where each RF signal source is configured to emit RF signals. The computer system then generates a stream of particle bursts to represent at least one of the emitted RF signals, and provides a visualization that shows the instantiated RF signal sources along with the generated particle bursts representing the emitted RF signals. In some cases, the visualization may be used to illustrate an anti-access, aerial denial (A2AD) environment. In other cases, the visualization may be used to illustrate network communications using particles, where each particle represents network data packets.
Embodiments are directed to visualizing electromagnetic (EM) particle emissions in a computer-generated virtual environment. In one scenario, a computer system accesses portions of data representing EM particle emissions emitted by a virtualized EM particle emitter. The computer system generates a particle visualization that includes at least a portion of the EM particle emissions being emitted from the virtualized EM particle emitter within the virtual environment. The particle visualization includes an indication of the EM particle emissions' interactions with other virtual or non-virtual elements in the virtual environment. The computer system then presents the generated particle visualization in the computer-generated virtual environment. In some cases, the computer system further receives user input intended to interact with virtual elements within the virtual environment. In response, the computer system updates the generated particle visualization based on the user's interaction with the virtual element.

The device includes a short range wireless transceiver which allows the status data to be communicated via a wireless connection to an external wireless communication device, whether the processor or programmable circuitry is in the powered on mode or the powered off mode. The wireless communication device, in turn, transmits the status data to a maintenance/repair/monitoring facility via a communication network. This facilitates monitoring of the device in a non-intrusive manner and streamlines maintenance of the device. The wireless communication device also receives information from the external communication device, including information relevant to the operation of the device, and updates the status data based on the received information. This facilitates updates to the device, as needed.

Isolated digital video interface receiver and method for isolating received digital video interface signals
Digital video signals are transmitted from a transmitter to a receiver via a digital video interface including shielded twisted pair cables that are surrounded by an over-braid shield. The over-braid shield is connected to a chassis ground at a transmitting end and the receiving end. An interface conveys the received signals to receiver processing circuitry. The interface is connected to an isolated ground, isolating the receiver processing circuitry. The twisted pairs are also connected to the isolated ground, such that a return current is forced back through the twisted pair cable shields rather than the over-braid shield. This reduces electromagnetic emissions and confines transients primarily to the over-braid shield.

A fault detection system is provided for a display system including an AMLCD. A video processor embeds encoded fault detection data within the digital video stream that is sent directly to the AMLCD. The fault detection data is embedded in such a manner that it is not displayed by the AMLCD. The fault detection data in the digital video stream received by the AMLCD is detected by the AMLCD and is then sent back to the video processor. The video processor compares what was sent with what is received to determine whether there is a difference which may be indicative of a fault in the AMLCD or the path of the digital video stream. As an additional check, the AMLCD may send timing error data to the video processor indicating whether the AMLCD is working properly. The video processor generates and outputs a fault flag to initiate a corrective action if a fault is detected in the AMLCD and/or the path of the digital video stream.
