Abstract: Beam scheduling strategy of maneuvering target track and track-and-search (TAS) in strong clutter environment for battlefield surveillance phased array radar is the hot spot in current research. The ground interacting multiple model joint probability data association tracking algorithm based on the prior information about target path and ground clutter is established. The dynamic TAS beam scheduling is achieved based on the target threat level and tracking accuracy of threat target. The TAS beam scheduling strategy based on the GIMMJPDA tracking algorithm, high threaten priority and target tracking accuracy for battlefield surveillance phased array radar has high efficiency of time utilization, which can be used in engineering application.
