Abstract
The paper describes a technique to compress 16 bit/pixel magnitude or 32 bit/pixel complex synthetic aperture radar (SAR) imagery without loss. The image is divided into its 16 or 32 individual bit-planes and each bit-plane is separately subjected to a raster scan to record the run-lengths of zeros and ones. The run-lengths are then coded using the CCITT Group 3 facsimile standard (a modified Huffman code). Performance is measured by comparing this technique to other lossless image compression techniques, such as JPEG-LS and JPEG-2000.
