A system determines absolute speed of a moving object. In AM, time of flight data over a time period is processed to determine ranges between the system and the moving object. The system performs linear regression analysis on the collected ranges to calculate the radial velocity. The system measures angular swivel rate of the system to determine tangential velocity. From the radial velocity and tangential velocity, the absolute speed can be calculated by taking the square root of the addition of the square of the radial velocity and square of the tangential velocity. In MM, the system calculates object distance, i.e. distance in the direction of travel, by subtracting the square of a pre-determined perpendicular distance L, perpendicular to the direction of travel, from a square of line-of-sight distance R, and taking square root of the result. Absolute speed is determined by calculating the slope of modified linear regression curve-fit.
