Other AbstractFully polarimetric microwave radiometer is a new type of passive microwave sensor for measuring ocean wind vector.Digital correlation technology is used inside it to get all the four Stokes parameters of ocean emission in this paper.Digital correlator is the main part of the fully polarimetric radiometer.In the paper,design of a novel digital correlator is presented.Two high-speed,dual A/D converters are used to sample four signals,and the sampling results are operated in FPGA-Vertex5 to make both self-and cross-correlation calculations.The testing results of the correlator are given.The sampling rate is 360 MHz with effective number of bits more than 7.2 bits in 8 bits resolution.For both 100 MHz and 150 MHz input,the correlation coefficient between the measurements and their theoretical results is more than 0.9999999.The whole power of digital correlator is 11.3 W.
