摘要
为了在毫米波雷达和干扰设备的电磁对抗试验中评估干扰机的干扰性能,提出并实现了一种基于GPS的毫米波单脉冲多模雷达的信号处理解决方案。针对步进频体制下发射信号随机抖动问题分析了产生的原因,给出了导致测距不准和目标抽取错误影响的数学推导,最后提出了一种消除随机抖动的方法,仿真结果证明了此方法的有效性。
To evaluate the performance of jamming equipment in the electromagnetic jamming experiment of millimeter wave radar and jamming equipment, an implementation method based on GPS was put forward by this article. Besides. the reason of random wobble of the signal transmitted and the math formula of the influence of error ranging and error one-dimension range profile in frequency stepped mode are given. At last. a method of eliminating random wobble is put forward and the result of simulation proves the validity of the method.
