讨论雷达接收机在多频干扰作用下产生的互调失真和交调失真，并介绍脉冲多普勒雷达接收机中三阶互调和抑制率，无假响应动态范围，无交调失真动态范围，干扰互调抑制度和干扰交调抑制度等参数的测试方式。

This paper discussed the problem of the intermodulation and cross-modulation distortions caused by multi-frequency interferences in the radar receiver, and at the same time introduced how to measure the third-order intermodulation rejection, non-spurious response dynamic range, non-cross-modulation distortion dynamic range on pulse Doppler radar receiver.
