摘要
微波遥感技术具有全天候、全天时的观测能力,已发展成为观测大气和地球表面的重要遥感手段,应用广泛。相比太阳同步(低)轨道,同步轨道微波遥感探测具有高实时性和大覆盖的特点,已成为微波遥感技术领域研究和发展的热点,在实时高分辨率侦查监测、中短期气象/海洋预报以及重大自然灾害监测等方面具有明显优势。文章分别对同步轨道微波辐射计技术、同步轨道降雨雷达技术和同步轨道SAR技术的需求和国内外发展现状进行了介绍,对所涉及到的关键技术及相应的解决途径进行了研究分析,并针对性地提出了下一步发展建议。
Benefiting from the capability of all-time and all-day observation, microwave remote sensing has become a significant and widely used method for atmospheric sounding and earth observing. When compared with sun-synchronous orbit observation,the microwave remote sensing in geostationary orbit( GEO) has notable features of high time resolution and wide coverage,so it has attracted plenty of attention both in scientific and industrial areas. In addition,using GEO microwave remote sensing has obvious advantages in fields of high resolution reconnaissance, medium -term meteorological/oceano-graphic forecast,and monitoring after major natural disaster. The scientific requirements and development status of geosta-tionary microwave radiometer,geostationary precipitation radar and geostationary synthetic aperture radar are illustrated in this paper. Then,the related key technologies and corresponding solutions are investigated. Finally,the suggestion for future development is proposed.
