Current Situation and Prospect of Microwave Remote Sensing in China

Characteristics of remote sensing instruments in visible,infrared and microwave bands were analyzed.Microwave remote sensing instruments are compensations of visible and in- frared sensors that they have the disadvantages of getting images in low efficiency,diffi- cultly obtaining characteristic information of objectives and achieving quantitative remote sensing.The function of microwave remote sensing instruments were pointed out.The de- velopment and application of airborne synthetic aperture side-looking radar,airborne mi- crowave radiometer,airborne microwave scatterometer,and airborne ocean radar altimeter in China were summarized.The achievements indicates that the airborne microwave remote sensing instruments have achieved practical level.It has been used in productive activities, scientific research,disaster prevention and mitigation research,etc.The situation of mi- crowave remote sensing instruments installed on world’s major earth observing satellite were listed.Microwave remote sensing instruments are being used more and more in earth observing activities because it can provide effective information in developing and utilizing sources,protecting the environment,preventing and mitigating disasters. In order to early achieve distinguish feature of spaceborne microwave remote sensing in our country,China should strengthen unified leadership in microwave remote sensing re- search and application,focus manpower and material resources to develop airborne practi- cal level,ground experiments and the theory of microwave remote sensing.
