The SAR Processing System Control Processor (SPS CP) computer program performs sequencing and job-control functions within the Alaska SAR Facility (ASF) [where "SAR" means "synthetic-aperture radar"]. SPS CP interacts with the Product-Distribution-and-Management (PDM) system of the ASF to receive processing orders as well as engineering and raw signal data. SPS CP provides a graphical user interface for operator control and performs job-sequencing functions to orchestrate the Raw Data Scanners (RDS) and SAR processors of the ASF to produce image data products. It is capable of displaying images to support visual data-product-quality checks. It is capable of recovering from errors caused by various abnormal processing events. The interfaces between SPS CP and the raw-data scanners and SAR processors are based on a client-server model with sockets and multithreading. SPS CP is hosted on SGI Origin or Challenge computers; the interfaces with raw data scanners and SAR processors are hosted on SGI Challenge, DEC Alpha, IBM SP-2, and Compaq computers. This program has been supporting ASF operations for over five years and its capabilities have been continuously enhanced to enable both large and small scientific-processing campaigns that have included mapping of the Amazon rain forest, the Antarctic Mapping Mission, and the Arctic Snapshot Mission.
