基于三次样条插值的非线性调频雷达信号设计
Nonlinear Frequency_modulation Radar Signal Design Based on the Cubic Spline Interpolated
摘要
Abstract
Based on the general design principle of nonlinear frequency modulated radar signal waveform (NLFM),Hamming window was chosen as the window function to design nonlinear frequence modulation (NLFM) radar signal by using the cubic spline interpolation method to solve the inverse function,the designed NLFM radar signal has been pulsed compression and the pulse compression waveform was simulated using matlab,the results obtained by Cubic spline interpolation method has smaller error than the results obtained by polynomial fitting to solve the inverse function and the main-to-side lobe ratio of NLFM pulse compression waveform reaches up to 64.8 dB.关键词
