Fine spectral band microwave radiometer system with adjustable channel parameters

The invention discloses a fine spectral band microwave radiometer system with adjustable channel parameters, and the system comprises an antenna subsystem which is used for controlling the conical scanning of an antenna, converting a received microwave signal into signals of different frequency bands, and outputting the signals; a receiver subsystem which is used for carrying out detection acquisition or frequency spectrum subdivision processing on the received signals of each frequency band and outputting remote sensing data of each channel; a comprehensive processor which is used for sendingthe remote sensing data outputted by the receiver subsystem to a satellite platform; and receiving a control instruction of the satellite platform, and completing the control of the fine spectrum microwave radiometer system with adjustable channel parameters according to the control instruction. The system has the characteristics of multiple channels, high spectral resolution and the like, and the atmospheric vertical te
