The development of space-borne commercial SAR system and networking technology
摘要
Abstract
In recent years,significant progress has been made in spaceborne commercial SAR technology and networking technology.Spaceborne SAR includes two main systems,phased array SAR and reflector SAR,both of which have been widely used.This paper discusses the development trend of spaceborne SAR and the application prospects of its networking technology.Multi-satellite networking technology has achieved wider coverage and higher temporal resolution,while the use of inter-satellite links has improved data processing and downlink capabilities.In addition,with the rapid development of commercial SAR constellation technology,the application of high temporal and spatial resolution SAR has become possible.In general,the innovation of spaceborne SAR technology and networking technology has opened up broader prospects for satellite remote sensing applications and promoted its widespread commercial application.关键词
