Pulse compression as one of the key technologies for the dual-frequency precipitation radar (DPR), which will be installed on Chinese FengYun-3 (FY3) Precipitation Measurement Satellite, is being studied. Since the backscattered echo of the sea surface is much stronger than the rain echo, the surface clutter can also contaminate the rain echo through the range sidelobe. In this paper, the model of...
Spaceborne microwave scatterometers have successfully provided global ocean surface wind field for two decades. Ocean wind data have become as a critical tool utilized daily by operational weather forecast and warming centers around the world. However current scatterometers still can not satisfy the requirement of achieve ocean wind vectors in nearly all weather and all wind conditions. The wind field...
The 3D imaging microwave altimeter is a proposed instrument for obtaining centimeter level accuracy of topography for ocean and meter-level accuracy of topography for land. In order to ensure the normal operation of the system and improve its performance, the EMI and EMC problems should be considered in design phase. In this paper, the architecture of altimeter system is shown and the main EMI sources...
