Other AbstractFully polarimetric microwave radiometer is a new type of passive sensors for sea surface wind measure.Four Stokes parameters are measured to get the ocean surface field by digital correlator in digital polarization radiometer.As the core part of radiometer,broadband digital correlator is introduced in the paper.Dual-polarized channels are translated to IQ transformer to output two pairs of orthogonal signals.Four channels are sampled by four A/D converters produced in China at 2.2 Ghz rate with the sampling results translated to the newest Field-Programmable Gate Array(FPGA)-Virtex5 by multiplexer.More multiplexing and correlating operation are completed in FPGA.The structure of interfacing circuit,data processing and circuit measurement are presented in detail.
