| Abstract: | 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. |
