The frequency sweep nonlinearity distortion of LFM signals is one of the most important factors that affect the performance of LFM radars. In this paper, the mathematical models for periodic frequency deviation distortion and nonperiodic frequency deviation distortion of LFM signals are made. And the effects of these two types of FM nonlinearity of LFM signals on the matched-filtering pulse-compression performance of LFM radars are investigated profoundly. The computer simulation experiments are performed by using MATLAB language. Also the results are acquired and prove the correctness of preceding theoretical analyses. All the conclusions obtained theoretically and experimentally, provide lots of indispensable theoretical basis and important experiential reference for the linearity correction of LFM signals, the design of wideband (WB) or ultra wideband (UWB) LFM radars, and the performance evaluation and performance optimization of LFM radars.
