Abstract
A system and method to perform target tracking with a radar system that uses a Kalman filter include predicting a predicted target position of a target detected by the radar system in a frame. The frame is a period of time to transmit from every transmit element of the radar system in turn and receive the reflections from a range of the target. The method also includes determining an actual target position of the target detected by the radar system based on reflections received by the radar system for the frame, and computing a process noise covariance matrix Q for a next frame, immediately following the frame, based on the predicted target position and the actual target position. Predicting a position of the target in the next frame is based on the process noise covariance matrix Q.
