This paper describes the influence of FM channel linear distortion ( amplitude-frequency characteristics distortion) on group-frequency signals ( modulated signal), which makes the group-frequency signals produce amplitude-frequency charateristics distortion and amplitude non linear distortion. 本文论述了调频通道的线性失真(幅频特性失真)对群频信号(调制信号)的影响&使群频信号产生了幅频特性失真和振幅非线性失真。
The influence of amplitude-frequency characteristics distortion in radar channels on its per-formance is studied in theory. 从理论上探讨了雷达系统信道幅频特性畸变对其性能的影响。
