Some SAR processing results using auto-focusing
Abstract
A digital SAR processor developed to produce images from SAR raw data is described. A method for obtaining automatic focusing in azimuth compression is presented with a discussion of inherent limitations. Examples of processed imagery are shown. Results for land areas are good. A combination of estimation of orbit parameters from SAR raw data and externally supplied orbit data provides the information necessary for image processing. Distortions in the data can be corrected by using maximum contrast.
