| Abstract: | To solve the deficiency of traditional Fourier transform on radar echo signal,the approach using wavelet transform is proposed.Based on analyzing the principle of the wavelet transform,this article discusses the principle and the methods of applying the wavelet transform in restraining noise of the radar echo signal.Imitating experiments and the data show that the method has improved wave form quality of radar echo signal and raised the rate of target recognition.We can conclude that the method is available... |
