Abstract :
The K/Ka-Band Microwave Radiometer (MWR) on-board Aquarius/SAC-D mission is described here with details on its radiometric calibration. The calibration is separated in two major instrument parts viz. receiver and antenna switch-matrix. An on-orbit calibration using Naval Research Laboratory´s WindSat radiometer is used to determine antenna pattern correction coefficients and residual biases.
