相控阵雷达资源受限时搜索参数调整策略

Search Parameter Adjustment Strategy for Phased Array Radar under Limited Resource

相控阵雷达最主要的工作方式为搜索和跟踪,针对跟踪任务抢占雷达总资源导致搜索性能下降的问题,文中在搜索空域需要适时进行调整的条件下,考虑到扫描过程中产生的波束展宽效应,提出了以空域覆盖系数为优化函数的资源受限时的搜索性能优化模型,给出了波束宽度调整(ABW)、观测空域调整(AOA)和波束宽度和观测空域联合调整(ABWAOA)三种策略,通过仿真比较了三种参数调整策略的搜索性能,结果表明ABWAOA策略的调度性能最优。

The main work mode of phased array radar is search and tracking, under the conditions that the search performance decreases due to the preemption of radar resources by tracking tasks and the search space needs to be adjusted in time, an optimization model for searching performance under resource constraints with the airspace coverage coefficient as the optimization functions is proposed with considering the effect of the broadening of the beam width during the scanning process. Finally three strategies of adjusting beam width(ABW), adjusting observation airspace(AOA) and adjusting beam width and observation airspace(ABWAOA) are provided, the performance of each strategy is compared by simulation, the results show that ASBAOA strategy has the optimal scheduling performance.
