本程序对线性调频信号进行了仿真、时域分析以及频域分析；在不同时宽带宽积TBP下比较驻定相位法与原信号的符合程度；不同过采样率对线性调频信号的恢复程度。(This procedure is simulated, time domain analysis and frequency domain analysis of linear FM signal; at the same time bandwidth product TBP with stationary phase method compared with the original signal; the different sampling rate the degree of recovery of the linear FM signal.)
