Microwave Remote Sensing has developed rapidly during last decades,and become a leading method in remote sensing techniques,since its unique features,capability to penetrate clouds and to some extent rain due to its independence from the sun as a source of illumination and other important properties different from visible and IR frequency bands Microwave remote sensing became a key means for obtaining information from ocean,atmosphere and land in global scale The frequency range using for microwave remote sensing is extending to millimeter and submillimeter bands To meet the wide requirements,China enhanced the microwave remote sensing research during last two decades and has got many achievements In this paper,the microwave remote sensing activities,its achievement,and the state of the arts are described, some strategic suggestions in future development given. Some concepts of space borne system are discussed, and the research areas to which should give priority to develop in national R&D plan suggested. A new concept of remote sensing—a comprehensive electromagnetic sensing system has been suggested to improve remote sensing capability [
