Abstract:

For influenced by calibration source, the reflection coefficient of microwave radiometer receiver is studied to improve the accuracy of the microwave radiometer. The error calculation formula and system noise formula are also provided. Utilizing 3165 GHz microwave radiometer to certify the inverse radiation of calibration source, it is shown that the reflection coefficient is influenced by inverse radiation. Therefore, the missmatch factor and the system noise increasing are influenced by reflection coefficient.

Key words: microwave radiometer, calibration source, reflection coefficient, inverse radiation, missmatch factor
