A Detection Method of Radar Signal by Wavelet Transforms

In this paper, an effective detection method of radar signal is presented based on the wavelet analysis. The purpose of this paper is to provide the review of the wavelet analysis research and to detect radar target from radar echo. The theory of wavelet analysis is presented including continuous and discrete wavelet transform. Then specific application, namely radar target detection is presented. In this paper, using wavelet transform to preprocess the radar echo, we are able to obtain multiple data series at different scales of the wavelet transform. These multiple data series can then be used as input to sensors of independent component analysis for detection of a single independent source. The proposed method is applied to radar target detection using a real signal series. It is demonstrated that the method in combination with wavelet transform is effective with feasible result. It has greater theoretical significance and actual applied value in regarded to radar signal processing and target identifying in our aerial defense weapon system.
