在高频地波雷达探测系统中，接收系统的任务是将目标回波信号从很强的杂波和噪声干扰中提取出来，使得后续的目标信息提取得以进行。本课题从高频地波雷达接收机的工作原理出发，分析了高性能接收系统设计中的一些问题并提出了相应的解决方案。(In the high-frequency surface wave radar detection system, the receiving system of the target echo signal is extracted from the strong clutter and noise, making the subsequent target information extraction to be carried out. The working principle of the subject from the high-frequency surface wave radar receiver, this paper analyzes some of the problems in the design of high-performance receiver system and propose appropriate solutions.)
