针对高重频 PD 雷达测距模糊，不能直接利用距离信息抗距离遮挡的问题，提出了一种高重频雷达导引头变PRF 抗遮挡方法；对限定频率范围内的 PRF 进行分析，根据优选策略确定一组具备抗遮挡能力的 PRF，针对载机能否提供较精确的初始装订距离，分别设计不同的 PRF 切换方式，由导引头软件控制优选 PRF 组按照不同的方式切换工作，完成抗遮挡任务；仿真试验结果表明：提出的方法具有较好的抗遮挡性能。

We proposed an avoidance eclipse method using alterable PRF for HPRF radar seeker to solve the problem that the ambiguous range information cannot be used directly to avoid eclipse. Firstly,the PRFs in limited range were analyzed and a couple of PRFs could avoid eclipse were selected. Secondly, two switch methods were designed according to whether the air-borne could provide precise initial distance or not. Lastly,the selected couple of PRFs were used to work based on the two switch methods. The result shows that the proposed method has a good avoidance eclipse performance.
