Shipborne radar echo Signal Denoising Based on Improved Threshold and Shrinkage Function
In order to denoise shipborne radar (9GHz pulse radar) echo signal in distortion-free, smooth, and less loss, A improved threshold and shrinkage function are proposed in this paper based on the Multi-analysis wavelet threshold denosing. The denoising effects of different shrinkage function for shipborne radar echo signal were compared. The results of experiment show that better SNR and similarity and smoothness and less loss can be reached by using the proposed function to shipborne radar echo signal.
