Abstract | Microwave radiometer is a kind of passive microwave remote sensor. Generally microwave radiometer is considered passively receiving radiation from the object and no energy radiate from the antenna to the outside. In the practical system, the components of radiometer really have thermal noise and radiate energy in the reverse direction. In another case, the reverse radiation comes from the mismatch of the components between the antenna to the receiver system. The energy radiates to the outside through antenna, and reflected back by the objects and received by antenna again. The value of reverse radiative temperature is related to the noise of the receiver and components of the receiver front-end. The reverse radiative temperature in the system will affect the accuracy of the calibration of microwave radiometer and the ground-based microwave radiative measurements near nadir angle. |
