Unmanned aerial vehicle-borne L-band phased-array antenna microwave radiometer system

The invention provides an unmanned aerial vehicle-borne L-band phased-array antenna microwave radiometer system. The unmanned aerial vehicle-borne L-band phased-array antenna microwave radiometer system comprises a system control unit, a moving direction control unit, a phased-array antenna, a receiver and an information acquisition unit, wherein the moving direction control unit is used for sending an electrical scanning instruction to the phased-array antenna after a working starting signal is received and sending a scanning wave position number to the information acquisition unit, the phased-array antenna is used for acquiring remote sensing signals at different scanning positions by different electrical scanning beams and sending the remote sensing signals to the receiver, the receiveris used for generating and sending remote sensing data to the information acquisition unit after filtering, frequency conversion and amplification are performed on the remote sensing signals, the information acquisition unit
