Design of 5 GHz Bandwidth Digital Correlator in Fully Polarimetric Microwave Radiometer

Lu Hao1,2,Wang Zhenzhan1(1.Key Laboratory of Microwave Remote Senging,Chinese Academy of Sciences, Beijing 100190,China;2.Graduate University of Chinese Academy of Sciences,Beijing 100049,China)  
To get the four Stokes vectors and ocean surface fields,fully polarimetric microwave radiometer can adopt multi-channel digital correlation technology including the self-correlation and cross-correlation between the horizontal and vertical polarization signals.Fully polarimetric microwave radiometer is a new-type of microwave remote sensors.Digital correlation is the core part of the system.A novel digital correlation is introduced in this study.Four high-speed A/D converters are used to sample the signals of four channels with the results translated to multiplexers for decelerating.The latest Field-Programmable Gate Array(FPGA)-Virtex5 fabricated by Xilinx has been used to complete the correlation,meanwhile,the results are translated to PC in time.The new-type of correlator can process data with up to 5 GHz bandwidth.
