"A novel software-based synthetic-aperture radar (SAR) processor is described. The processor is capable of routinely producing a variety of data products from data acquired by either the SEASAT-A satellite-borne SAR or the Environmental Research Institute of Michigan (ERIM) airborne, dual frequency/dual polarization, SAR. The SAR processor described is adaptable in that it can be configured to process imagery from any SAR system that maintains the range coding constant from pulse-to-pulse. A description of the equations that were used to implement the SAR processor is given as are details of the processor configuration. It is shown that the processor consists of two main subsystems: a very general SAR processing subsystem; and a radar data product-specific support subsystem. It is described how the processor can be reconfigured by changes to parameter files, and how the processor modules communicate with each other by means of a data file structure. The hardware upon which the processor was programmed is briefly described, and timings for the various production products; generated using this hardware, are given. Examples of the image data products are also included in the description. Finally, specific comments are made with respect to extending the capabilities of the processor"--Abstract, page 1.
