In order to reduce the noise and clutter interference in navigation radar image, this paper proposes a method based on wavelet transform combined with morphology for radar image denoising by analyzing noise features and common image denoising algorithms. The multi-resolution characteristics of wavelet transform are used to analyze and process image details, and then combined with closed operation in morphology, the image details are retained while reducing the noise effectively. The experimental results show that this method has a good denoising result for radar image.
