Abstract: Allweather and alltime microwave (MW) remote sensing is one of the frontier areas for the spaceborne remote sensing and surveillance technologies. In this paper, a brief overview of Chinese development process of the spaceborne MW remote sensing technologies during several decades since the beginning of 1970’s is presented. It mainly includes the research and development of the programs of FengYun meterological and Oceanic satellites, and the synthetic aperture radars. It has shown how Chinese MW remote sensing is in great transition from the “stepfollowing” to reaching an advanced place. It is expected that in future 30 years Chinese spaceborne MW remote sensing can achieve more progress in leading the advances of MW remote sensing.
