合成孔径雷达问世以来,由于其特有的全天候、全天时成像的特点及其对一些地物的穿透性能,已广泛用于军事侦察、减灾防灾、农林、水文、地质、环境监测等方面。在90年代,合成孔径雷达技术有长足发展。前苏联金钢石卫星、欧洲遥感卫星1号、日本资源卫星1号、加拿大雷达卫星、美国航天飞机等携带合成孔径雷达升入天空后,实现了对地球的周期性、长期性探测,为军用与民用提供了丰富的数据源,为资源的勘查利用提供了科学依据。
Since the advent of Synthetic Aperture Radar, it has been widely used in military reconnaissance, disaster prevention and mitigation, agriculture and forestry, hydrology, geology and environmental monitoring due to its unique characteristics of all-weather and all-day imaging and its penetrating ability for some features. . In the 90s, synthetic aperture radar technology has made great progress. The former Soviet Union’s Diamond Satellite, the European Remote Sensing Satellite No. 1, Japan’s Resources Satellite No. 1, Canada’s Radar Satellite, the United States Space Shuttle and other synthetic aperture radar carrying into the sky, to achieve a periodic, long-term exploration of the earth, military Provide a rich data source with the civil, and provide a scientific basis for the exploration and utilization of resources.
