重视微波遥感是90年代遥感发展的特点之一。由于微波遥感具有全天候、全天时和一定穿透能力的特点,因此,受到各国遥感界的普遍重况。根据各国微波遥感计划的情况来看,90年代以微波遥感为主要内容的卫星、空间飞行器等将大为增加。美国除了在EOS计划中安排了近1/5的微波探测器而外,与EOS计划并行的SIR-C,SIR-D计划完全以主动式成像雷达的探测和研究为主。加拿大Radarsat卫星将带有C波段HH极化方向多性能合成孔径侧视雷达,主要用于监测极区冰的动力学成因。欧空局除在其第一颗卫星
Attention to microwave remote sensing is one of the characteristics of remote sensing development in the 90s. Microwave remote sensing has all-weather, all-day and certain penetrating ability, therefore, by the remote sensing community in general re-conditions. According to the situation of microwave remote sensing programs in various countries, there will be a great increase in satellites, space vehicles and the like that take microwave remote sensing as the main content in the 1990s. In addition to arranging nearly one-fifth of the microwave detectors in the EOS program, the SIR-C and SIR-D plans in parallel with the EOS plan are based exclusively on the detection and research of active imaging radars. Canada Radarsat satellite will have a C-band HH polarization direction of the multi-performance synthetic aperture side-looking radar, mainly used to monitor the dynamics of polar ice. ESA in addition to its first satellite
