High Efficiency Integrated Test Processing Technology and System for High Resolution SAR Satellite

Abstract

SAR satellite installation mounted test is an important part of satellite ground test. According to the current requirements of high-resolution SAR satellite ground test, as well as the characteristics of spaceborne SAR, such as high-resolution, large data volume and complex data type, firstly, the overall scheme architecture of integrated test system is studied and constructed based on the principles of standardization, scalability, automation and efficiency; Secondly, according to the characteristics of data processing tasks, function modules are divided and efficient processing algorithms are developed to adapt to parallel computing. Finally, the development of integrated test processing system and test run verification are carried out. Through the construction of an integrated test system based on high-performance computing, test management software as the platform and functional modules as the core, the rapid process design technology of efficient function module development and test data processing process, multi-stage, multi-type and multi-mode test data storage and management technology are broken through,it realizes the efficient processing, analysis and evaluation of massive test big data, which strongly supports the full test verification and successful development of high-resolution SAR satellite.
