A new microwave sensor in which active and passive mode sensors are working synergistically is designed for future China space projects. In the system the scatterometry, altimetry and radiometry functions are integrated technically. There are three operation modes and the mode combination can be selected in order of user requirement. The main modes are: ALT + RAD1, SCAT + RAD1, Multifrequency RAD, working at five frequency band (RAD2 - RAD6). Altimeter, Scatterometer and Radiometer RAD1, working at same ku band frequency and use a common antenna. The system design is based at operational airborne sensors which was in operation from early 1980. Main key problem of the system is solving during the design of this system is the mode combination technique, antenna technology, data management and system calibration.
