Abstract :
Radar image denoising with wavelet packets has been studied in this paper. We propose a recursive thresholding and reconstruction algorithm on wavelet packet coefficients to obtain a clear radar scan. Utilizing the same algorithm, we can estimate the noise variance as well. We illustrate the performance of the proposed approach with both synthesized and real radar images
