Abstract海洋风场是海洋与大气作用的重要参数之一。全极化微波辐射计是一种新型的微波遥感器。数字全极化微波辐射计采用多路数字相关技术,对水平和垂直极化信号进行相关处理,产生反演海面风场模型所需海面亮温Stokes矢量。详细介绍了数字全极化微波辐射计的系统设计方法,包括射频前端、中频段和数字相关器的设计。同时给出了系统内定标以及外定标方法。对数字全极化微波辐射计做了细致的理论分析和硬件实现设计。
Other AbstractOcean wind field is one of the important ocean and atmospheric parameters.Fully polarimetric microwave radiometer is a new type of microwave remote sensors.Multi-channel digital correlation technology is used in digital fully polarimetric microwave radiometer,with the horizontal and vertical polarization signal correlated to obtain brightness temperature Stokes vector for the inversion transformation of sea surface wind field model.This paper describes system design methods of polarimetric microwave radiometer,including RF front-end,the IF part and digital correlator.At the same time,the system internal and external calibration method are given,and detailed theoretical analysis and hardware design are introduced.
