Abstract:
Radar echo signals inevitably contain noise, and the presence of noise seriously interferes with the accurate analysis of radar echo signals. In order to improve the signal to noise ratio of radar echoes, the wavelet analysis is used to determine the wavelet function, the number of decomposition levels, the thresholds, and threshold quantization through experimental analysis. The results show that the wavelet analysis denoising method can effectively suppress the noises superimposed on radar echo signals, and the signal to noise ratio of radar echoes significantly increased after denoising, which is highly applicable.
