仿真了高斯白噪声，并通过巴特沃夫滤波器生成高斯色噪声(The gaussian noise was simulated and the gaussian noise was generated through the butterworth filter)

一种基于LFM和Barker码复合调制的雷达波形，理论上分析了该低截获雷达波形的组成。通过仿真得到复合调制信号的时域波形、频谱图和模糊函数图，与LFM信号和Barker码信号对比分析对复合调制雷达信号的距离和多普勒模糊函数、截获因子等进行了研究。(A radar waveform based on LFM and Barker code modulation is presented. The composition of the waveform is analyzed theoretically. The time domain waveform, spectrum and ambiguity function of the compound modulation signal are obtained by simulation. The range and Doppler ambiguity function and interception factor of the compound modulation radar signal are studied by comparing with LFM signal and Barker code signal.)
