摘　　要：针对复杂电磁环境下多体制雷达信号的实时有效跟踪问题,设计了可用于固定重频、脉间参差、脉组参差、重频抖动等多种模式的重频跟踪器,给出了仿真验证结果.该设计将多模雷达信号跟踪分解成多个固定重频跟踪支路进行处理,通过合成来适应复杂重频类型;在跟踪判断和波门预测中采用多种方式减小数据误差的影响.通过仿真和硬件测试验证了该设计的有效性.This paper focuses on the real-time effective tracking of multi-system radar signals in the case of complex electromagnetic environment by designing a PRI tracker used for multi-mode of fixed PRI, stagger PRI, irregular grouping RPI and jittered PRI and so on, and presenting the simulation results. In this design, this paper decomposes the tracking of multi-mode radar signals into the multi fixed PRIs tracking branches for processing, adapts them to the complex types of PRIs by the synthesizing them, and uses the multi ways to lower the influence of data errors in the tracking estimation and waves gate prediction. The effectiveness of this proposed design is proved by its simulation and hardware test.
