Oceanic Multiband Microwave Radiometer (OMMR) is a five-band and 10-channel remote sensor, which is designed for in-situ calibration and validation of HY-2 satellite’s scanning microwave radiometer. It was demanded to satisfy the requirements of providing higher accuracy brightness temperature data than those of microwave radiometer during its one-year lifetime. Due to its special operating condition on the platform and some unexpected interference that might be suffered in this period, an effective calibration method is necessary and critical. In this paper, the principle of OMMR internal calibration was introduced, and attentions were paid on the analyses of calibration result of tests both in laboratory and on the platform. By using these calibration results, the data from in-situ measurements on the platform are given and evaluated. |
