Design of denoising system for MMW radar echo signal
Zha Pin-de · Applied science and technology · 2006
Denoising system of MMW radar echo signal uses the DSP chip as core part,assisted with A/D transform,control unit in conjunction with communication with PC and.Since echo signal is unstable,the denoising effect of traditional Fourier transformation is not good.This paper adopts a denoising method with wavelet trimming threshold.The result indicates that the new denoising system the SNR and reduces the least mean-square error improves.
