合成孔径雷达在深空探测任务中的应用与发展趋势
Application and Development Trend of Synthetic Aperture Radar in Deep Space Exploration
摘要
Abstract
Synthetic Aperture radar(SAR),which uses airplane,satellites or other moving objects as the platform,has the ability of all-weather and all-time to observe.It has become a highly efficient method of remote sensing detection,and has been widely used in vari-ous fields,such as deep space exploration,military reconnaissance,topographic mapping,disaster monitoring,agricultural and forestry growth monitoring,ocean current observation and other fields.This article sorts out the SAR technology status,scientific objectives,and detection results of several SAR systems,which have been set up in deep space ex-plorations of foreign countries and areas.And it provides comparative analysis of SAR systems,including Veneras15 and 16,Magellan,Cassini,Chandrayaan-1/2 and LRO.The Pol-SAR(Polarization Synthetic Aperture Radar)is carried by the Chinese lunar explo-ration Chang'e-7(CE-7).Pol-SAR will lead the rapid development of China's deep space exploration technology.It is hoped that it can provide some help for China's deep space exploration in the future.At the same time,the development trends of spaceborne SAR are analyzed.Spaceborne SAR is gradually moving towards high-resolution,multi-parameters,multi-modes,multistatic imaging,lightweight and other aspects.It will eventually play a more important role in richer application fields.关键词
