The Calibration Procedure for ACMIR

ACMIR (an airborne C-band one-dimensional microwave interferometric radiometer) is proposed for area sea surface temperature (SST) measurement with high resolution and high accuracy. A good calibration of ACMIR is needed to provide accurate values of visibility, which is used to get the brightness temperature. In this paper, the calibration procedure of ACMIR is presented. The modeling of temperature compensation and loss correction is given to improve the calibration accuracy.
