基于相控阵雷达的群目标准自适应调度策略研究

Research on Quasi-Adaptive Scheduling Strategy for Tracking Group Target in Phased Array Radar

群目标是指空间间距、运动方向与速度基本一致的多目标集合,该集合内的目标具有平均电影特性。对这种特殊目标群的跟踪算法研究已经较为深入,但其调度策略研究尚存在很大欠缺。为此,根据相控阵雷达资源调度灵活的特点,针对群目标调度策略尚存在欠缺的问题,在分析了传统相控阵雷达调度策略的基础上,剖析了群目标的特性,提炼了群目标跟踪调度策略的要素。在此基础上,提出了相控阵雷达群目标跟踪准自适应调度策略,并进行了仿真分析。仿真结果表明,所提出的准自适应调度策略能够有效地提高相控阵雷达的跟踪能力。

Group target is a set of multiple targets with the same space gap, moving direction and speed, which has the feature of average film. Although the tracking algorithm of this special target group has been researched profoundly, there is vacancy for the scheduling strategy study of this group target. In order to solve the scheduling question, first, the traditional scheduling strategy of phased-array radar is analyzed according to its flexibility of resource scheduling and the shortage of group target scheduling. Then, the es- sential elements of the scheduling strategy for tracking group target are refined after analyzing the character- istic of the group target. Finally, quasi-adaptive scheduling strategy for tracking group target in phased-array radar is proposed on the basis of above analysis. The simulation result shows that the presented quasi-adap- tive scheduling strategy can effectively improve the tracking ability of phase-array radar.
