战场侦察相控阵雷达波束调度研究

Study of Beam Scheduling for Battlefield Surveillance Phased Array Radar

战场侦察相控阵雷达在强地杂波环境下对机动性目标跟踪和边跟踪边搜索(TAS)波束调度策略是当前研究的热点。利用地面杂波和目标路径等先验信息,建立了杂波环境下地面交互多模型联合概率数据互联(GIMMJPDA)多目标跟踪算法,在区分目标威胁度、不同威胁目标跟踪精度的基础上实现目标动态的TAS波束调度。经目标态势仿真验证,基于GIMMJPDA目标跟踪算法、高威胁优先级和目标跟踪精度基础上的战场侦察相控阵雷达TAS波束调度策略具有高的时间利用效率。

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 a- chieved 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.
