Remote Sensing techniques are powerful tools for many civilian and military applications. However, in many cases high spatial, radiometric and temporal resolutions are required, leading to a large amount of data to be transmitted and/or stored. Synthetic Aperture Radar (SAR) is able to produce high resolution coherent images of a scene in any light and weather condition. In this paper we introduce the use of the Discrete Anamorphic Stretch Transform (DAST) to perform near lossless data compression of complex valued SAR image. DAST is applied to actual SAR data demonstrating the effectiveness of the proposed technique.
