Multilook SAR Image Enhancement Using the Dual Tree Complex Wavelet Transform

Abstract

We discuss in this paper the enhancement of multilooks SAR images for the purpose of wave detection. The method is based on improving the contrast in the dual tree complex wavelet domain, while performing denoising simultaneously. We describe the particularities of Sentinel-1 Strip map multilooks ground range detected images with high resolution and present the advantages of the proposed SAR image enhancement method. Simulation results and comparisons with state of the art contrast enhancement and denoising methods highlight the benefits of the proposed solution.
