Paper Abstract

In this paper, the microwave radiometer with computer controlled automatic gain compensation is briefly introduced. By using this method, a four-frequency-band (1.4GHz, 3.0GHz, 5.4GHz, 10.0GHz) compact microwave radiometer machine is designed and developed. After showing the methods of selecting some parameters of the system, the paper gives out the system calibration equation, sensitivity and linear correlative coefficients. Finally, it presents the system test results of the long-term stability, the ability of gain compensation, and also the test results of some crops: wheat, corn, and bean.
