Based on the fact that a chirpradar signal has a strong coupling between time and velocity, a deceptive jamming technique with shift frequency is proposed.
本文基于线性调频脉压信号在时间和多卜勒频率间存在强耦合的事实，提出用移频干扰实现欺骗干扰的方法。

A method for surpressing RFI in a chirpradar based on averaging range spectrum is developed, by averaging range spectra, the RFI can be detected and suppressed in time-frequency domain.
The paper discusses a method of identifying chirp signals and measuring its parameters and analyses the various responds which the general radar and chirp signals passed the SAW diverse delay.
