摘　　要：从产生射频Chirp信号的基本原理入手,分析了载波信号泄漏的机理以及带载漏的射频Chirp信号是如何产生的;研究了功率放大器的非线性对伴有载漏的射频Chirp信号幅频和相频特性失真的影响,以及失真后的信号脉冲压缩的结果。提出了一种有效的校正Chirp信号谱的方法。This paper start with generating radio frequency chirp signal fundamental principles,analysis leaking′ mechanism of carrier signal as well as how generating of with carrier-leaking radio frequency chirp signal,research nonlinear effects of power amplifieries on both amplitude and phase of a radio chirp signal with carrier-leaking,at the same time,we analysis also pulse compression results of distortion chirp signal.At last,we put forward a sort of effective analogy circuit method of correcting chirp signal ...
