Rapid and reliable decisions about the onset and termination of maneuvers are critical for accurate tracking of maneuvering targets. Given the appropriate filter model, the use of multiple sensors of different capabilities and strengths can improve the quality and the reliability of the tracking system A multisensor tracking system where the usage of the image sensor is two fold is presented. First, if is used to perform maneuver detection using minimum computation and storage. Second, its bearing and elevation measurements are used along with 3-D radar observations to improve the tracking quality. The advantages of the proposed multisensor tracking system are discussed and demonstrated via simulations.
