Behavior Subtraction applied to radar

An algorithm developed for optical images has been applied to radar data. The algorithm, Behavior Subtraction, is based on capturing the dynamics of a scene and detecting anomalous behavior. The radar application is the detection of small surface targets at sea. The sea surface yields the expected stable background dynamics, while a surface target will change the local dynamics due to its own motion. The results of the new algorithm have been compared with the more traditional STAP algorithm.
