线性调频信号是典型的脉冲压缩信号，在雷达波形设计中要重要的作用。本实例给出了调频雷达中混入正弦波噪声和高斯噪声时如何抑制噪声从而恢复调频信号的过程(LFM signal is a typical pulse compression signal, the radar waveform design to an important role. This example shows the sine wave frequency modulated radar mixed with noise and Gaussian noise, how to suppress the noise FM signal to the process of recovery)
