本文提出了一种用于线性调频连续波(LFM-CW)雷达的信号处理新方法.该方法用带通滤波器在频域内实现差拍信号的距离分段,然后用第一距离段所需采样率对每个距离段进行采样和FFT处理。在距离分辨单元数很大时,这种方法可以大大降低LFM-CW雷达对信号处理器的要求。
A new signal processing method for LFM-CW radar is proposed in this paper. This method uses a band-pass filter to segment the distance of the beat signal in the frequency domain and then uses the first distance Sampling rate Each distance segment is sampled and FFT processed. This method can greatly reduce the signal processor requirements of the LFM-CW radar when the number of distance resolution units is large.
