伪随机码调制连续波雷达泄漏信号抑制途径

介绍了连续波雷达针对泄漏信号的设计考虑和几种比较实用的泄露信号抑制方法。泄漏问题是连续波雷达设计必须考虑和解决的,接收前端增益应根据泄露信号电平来设计,天线的隔离度应保证接收机工作与线性状态。几种泄露抑制方法大多做过专题试验,可供参考。

The Methods of Leakage Signal Suppression in CW PN Code Radar

The design consideration for the leakage problem in CW radar is introduced and several practical methods for leakage signal suppression are analyzed in the paper. The leakage problem is the major problem for CW radar to resolve. It is necessary that the gain of receiver front-end should be designed according to the power of leakage signal. The isolation between the transmitter antenna and receiver antenna should ensure that the receiver works in the linear status. These methods for leakage suppression introduced in the paper were tested and can supply reference for practical application.
