Abstract

The CAS C-band interferometric synthetic aperture radiometer is a thinned array microwave radiometer with 6-channels and 11 analogue complex correlators. And the real aperture resolution cell in the cross track direction will be fractionized into 21 sub-cells. The coherent/incoherent calibration networks are designed to enable a calibration to correct the effect of system noise and channel imbalance. Some test results are presented
