基于matlab仿真雷达信号的脉冲压缩过程。产生一个线性调频信号，接受雷达回波中频采样频率为40MHz，中频进行正交下变频。在13.5km出有一个点目标，仿真雷达的脉冲压缩处理。-Matlab simulation of the radar signal pulse compression process. A linear FM signal, to accept the radar echo IF sampling frequency of 40MHz, IF quadrature down

通过调节载波频率可使外差法产生的差频在零频率点附近变动，从而使得双稳系统的输出信号发生特征极为明显的变化，为频率检测提供可靠的检测依据。(By adjusting the carrier frequency, the difference frequency produced by the heterodyne can be changed near the zero frequency point, which makes the output signal of the bistable s
