随着微波遥感技术在国民经济发展、环境和灾害监测、资源勘探、科学研究以及军事中应用的不断深入，这一技术正在经历着前所未有的发展。文章就当前微波遥感发展的若干前沿技术，例如高性能和新型机理、更高频率的开拓、全电磁波综合探测、小型化以及虚拟探测等进行了分析论述，重点介绍了三维成像雷达高度计、干涉式综合孔经微波辐射计以及虚拟探测技术。最后介绍了全球地形测量编队小卫星的设想。

The technology of microwave remote sensing is now experiencing a rapid development never before as microwave remote sensing plays a more and more important role in economic development, environment and disaster monitoring, resource detecting, scientific research and military applications. In this paper, several up to date technologies in microwave remote sensing are discused, such as high performance and new mechanism developing, higher frequency expanding, synthetic measurement using complete electromagnetic band, miniaturization of sensors, and virtual space borne detecting and monitoring. Detailed introductions to 3D imaging radar altimeter, interferometric synthetic radiometer and virtual remote sensing are given. At the last, the authors propose a tentative idea of global topography measurement using small satellite constellation, which can be composed of two satellites, three satellites or four satellites.
