Then after amplitudelimiting, to be preamplified, demodulated, bandpass filtered, the doppler frequency shift signal is extracted.
经过限幅保护，接收放大，检波和带通滤波后，将多普勒频移信号提取出来。

Since the false target jamming will cause D/A converter overflowing, the thesis also studies the influence to false target jamming profile by D/A quantizing and amplitudelimiting.
The invention can implement amplitude-limiting function without affecting the posterior demodulation, voltage stabilization, and normal operation of the clock and the reset circuit.
