舰载相控阵雷达跟踪模式收发波形时间分配方法

A transmitting-receiving waveform time distribution algorithm for shipborne phased array radar's track mode

舰载相控阵雷达作为多功能雷达可以大范围空域海域内预警搜索,又可同时快速捕获跟踪多个目标,其多目标随机跟踪能力是相控阵体制有别于非相控阵体制的突出优势。本文提出嵌入分层算法改进相控阵雷达的收发波形时间分配效率,利用待跟踪目标先验距离信息确定回波延迟,形成跟踪目标对应的嵌入式或并行式收发时序。创新的时间分配方法简洁有效、兼容传统模式,较好地提高雷达探测时效,数字仿真验证相控阵雷达收发波形时间分配的高时效性。

The shipborne phased array radars mostly are utilized as multifunctional radar,which can search,and track multiple targets meanwhile.Especially,multiple targets track apparently is the most advantage over other mechanical scanning radars.The paper has presents the embedded and layered hierarchy algorithm to improve the time distribution efficiency for transmitting and receiving waveforms.Based on the prior information of echo delay corresponding tracking targets,the transmitting pulse and receiving pulse are embedded or paralleled;the algorithm has improved the radar time efficiency.The simulation results of the last part have verified the conclusion.
