摘　　要：非线性调频脉压线是为雷达系统提供非线性调频信号的特殊器件,该文介绍了这种器件的脉压机理、给出了调频函数表达式和样品实测波形图,探讨了提高旁瓣抑制的途径和研究中存在的问题。Non-linear FM pulse suppression delay line is used to generate non-linear FM signal especially for radar system. Working principal of the device, expression of FM function, and the measured waveform is given in the paper. The way to improve the side-lobe suppression and some other problems during the investigation is also discussed in the paper.
