AbstractAs the core part of fully polarization radiometer, the digital correlator is used to make correlation of polarization channels to get all the stokes parameters. Based on the newest Field-Programmable Gate Array (FPGA)-Virtex6 made by Xilinx and high-speed A / D converter (ADC12D1800), design method of digital correlator is introduced in the paper with bandwidth of 1.6 GHz with 12 bit resolution. The effect number of bit in the system that has been completed is above 9 bit. Different with the other correlator, the novel correlator is used to make dual frequency-band correlation to output two group of stokes parameters. The structure of interfacing circuit, data processing and control system of the main modules are presented in detail. © 2012 Springer-Verlag Berlin Heidelberg.; As the core part of fully polarization radiometer, the digital correlator is used to make correlation of polarization channels to get all the stokes parameters.
