摘　　要：研究了非线性调频信号波形设计方法。根据调频函数模型,提出利用数据拟合的方法设计非线性调频信号。与其他方法比较,该方法设计的非线性调频信号距离副瓣低、主瓣展宽小,实验结果证明该方法的有效性。This paper studies the design methods of the nonlinear frequency modulation signal waveform.According to the frequency modulation function mode,this paper proposes to design the nonlinear frequency modulation（NLFM） signal using the data fitting method.Compared with other methods,the NLFM signal designed by this method has lower range-sidelobe and smaller main-lobe stretch,the experiment results demonstrate the validity of this method.

关 键 词：非线性调频 调频函数 曲线拟合
