介绍了雷达重复频率变化对目标跟踪的影响以及雷达重复频率设置的依据,分析了常规重复频率设置带来的目标盲速、速度分辨力较低等问题,提出了一种基于目标特性自适应重频变化的目标跟踪方法。该方法能够在保证距离测量单值性的同时避免目标盲速的产生,更好地发挥雷达综合性能。最后对基于目标特性的重复频率选择进行了仿真,证明了该方法的可行性。

This paper introduces the influence of radar repetition frequency change on target tracking and the basis of setting radar repetition frequency, analyzes the problems of low target blind speed and speed resolution caused by conventional repetition frequency setting, proposes a target tracking method based on the repetition frequency varying with target characteristics adaptively.The method can ensure the single value of range measurement and avoid the occurrence of target blind speed, so as to better play the comprehensive performance of radar.Finally, the simulation of repetition frequency selection based on target characteristics is performed, which proves the feasibility of this method.
