Predesign of the Wind Field Measuring Radar for Feng Yun-3E Meteorological Satellite

摘要

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 measuring radar (WIFIR) onboard Chinese FengYun-3E meteorological satellite is being developed to attempt to overcome their shortcomings. This paper describes the predesign of the WIFIR, including the mission requirements, system design, and performance analysis.
