A radar system uses multiple nulls to improve detection capabilities. Multiple radar pulses are transmitted and or received, each with a different null pattern. The returns from each pulse are averaged together to form a null window that is less noisy and potentially wider than a single null pattern. This approach can improve the signal-to-noise ratio and make it easier to detect objects of interest. The system may generate individual pulses from an AESA divided into several subarrays. Each subarray produces a pulse with a null in a different location in the radiation pattern centered about a location of interest. The contemporaneous return signals are averaged together.

LANGUAGE MODELS FOR AUTOMATIC MICROBENCHMARK GENERATION
Disclosed is a method of training a language model to generate “microbenchmarks” in which the training data is specifically associated with certain microarchitecture characteristics that the “microbenchmarks” are designed for testing. Also disclosed are language models that have been trained in this manner, and the corresponding use thereof to generate “microbenchmarks”.
An on aircraft computer system records and analyzes biometric data to identify indicia of impaired performance, such as pilot fatigue, attention tunneling, or cognitive overload. Such impairment is identified by alterations in pilot gaze or eye movement, head movement, facial parameters, eye lid position, heart rate, breathing, or brain wave patterns. Appropriate corrective action is applied based on the type of impaired performance identified, including altering a level of automation, contacting a ground dispatcher or ground pilot, or contacting a co-pilot or other crew member. Biometric data is continuously logged and correlated with data from other avionics systems to refine formulas relating biometric data to states of alertness and crew rest procedures.
An aircraft-based system and method for automated reporting and logging of aircraft maintenance events receives flight deck effects (FDEs) with correlated maintenance messages indicating maintenance statuses (e.g., faults and/or failures) and/or Air Transport Association (ATA) classifications for each reporting aircraft system, subsystem or component. The logging system generates event messages based on each received FDE, predicting additional information based on the correlated maintenance message such as recommended maintenance actions, replacement parts or components, and/or Minimum Equipment List (MEL) actions associated with a component fault or failure. Event messages are automatically transmitted via datalink to ground-based maintenance and dispatch. Further, event messages are automatically logged to an aircraft maintenance log.
An augmented reality system in an air traffic control tower receives data from multiple airfield sensors and from local aircraft and correlates the data in space and time. Features of the airfield are rendered visually in an augmented reality headset during low visibility conditions. The augmented reality system renders visualizations of aircraft and may render data from the aircraft to coincide with the visualizations. The augmented reality system may receive data from systems within the air traffic control tower, commonly rendered on displays in the air traffic control tower and rendered such data within the augmented reality display.
A system may include a processor configured to: (a) obtain parameters; (b) based on the parameters, update flight-state data associated with an aircraft; (c) obtain a trained machine learning (ML) model; (d) based at least on the updated flight-state data and the trained ML model, infer a direction from a current cell for a reroute; (e) based on the inferred direction and the updated flight-state data, set the current cell and identify neighboring cells; (f) calculate an optimal next cell by using a shortest path finding (SPF) algorithm to select the optimal next cell from the neighboring cells; (g) iteratively repeat steps (d) through (f) such that the current cell is set as the optimal next cell until a goal state is reached; (h) construct a re-route using optimal cells iteratively calculated in step (f); and (i) output the re-route.
A method is disclosed herein. The method includes determining, by a processor, a first time value in response to a switch being actuated a first time by a first striker, determining, by the processor, a second time value in response to the switch being actuated a second time by a second striker, the second striker disposed a first distance from the first striker and the second time value being after the first time value, calculating, by the processor, a change in time between the first time value and the second time value, and adjusting, by the processor, a timing sequence based on the change in time.
A radar system including an AESA illuminates a target with a first pulse for a desired beam pointing angle (azimuth and elevation). The AESA then illuminates the target with a second pulse for the desired pointing angle, the second pulse defining a radiation pattern with a main beam in phase with the first pulse, but side lobes that are out of phase. The radar system receives return signals and combines the return signals to null the side lobes by the principle of superposition. The radar processing unit is time synced such that the pulse-pair is interpreted as a single ultra-low level side lobe return radiation pattern.
A method is disclosed herein. The method includes receiving, by a processor, a first acceleration data from an accelerometer, calculating, by the processor, a change in velocity based on the first acceleration data, the change in velocity being calculated over a first period of time, and adjusting, by the processor, a timing sequence based on the change in velocity.

A system and related method for multiple-sensitivity optical phase modulation splits an optical carrier generated by a photonic source into at least two copies and directs the copies (e.g., via optical circulators or polarization rotators) to an electro-optical (EO) phase modulator such that the phase modulator phase-modulates each optical copy according to a received radio frequency (RF) signal of interest based on characteristics distinct to each optical copy (e.g., optical path direction, signal polarization) that provide for phase modulation of each optical copy at a different sensitivity voltage. The variably modified optical copies are directed to a photonic processor for further signal processing in the optical domain.
A motion planning system and method receives requests for routing a set of dissimilar aircraft through a defined airspace. Each aircraft has a starting and destination position relative to the airspace. A start state is based on the earliest start, and a goal state on the destination. The system connects start and goal states via a sequence of next states by projecting each state incrementally forward in time. Candidate next states include all possible next paths to a next position of each aircraft combined with next paths and positions of its neighbors, with unsafe next states culled from the set. Remaining next states are prioritized on the basis of aggregate system cost for all next paths and an estimated system cost to achieve the goal state, and an optimal next state is added to the sequence. When the goal state is achieved, optimal flight plans are generated for each aircraft.
