Abstract :
Correlation radiometer is the basic unit of interferometer or full polarization radiometer which can obtain the correlation of two receiving channels. The paper presents a novel receiving configuration of correlation radiometer using the digital signal processing to fulfill the IQ demodulation and acquire the band of application requirement exactly. This new receiving configuration can eliminate the quadrature errors which can simplify the calibration procedure and acquire exact receiving band which can improve the consistence of multiple parallel receiving channels. This novel receiving configuration which has been applied in LX-band Full Polarization Aperture Synthesis Microwave Radiometer (FPASMR) establishes the basis of spaceborne engineering application in the future.
