Digital control device based on microprocessor ARM (Advanced RISC Machines) and radar active calibrator

The invention provides a digital control device based on a microprocessor ARM (Advanced RISC Machines), which is used for controlling a microwave assembly of a radar active calibrator works between a self-calibration mode and a transmission mode. Under the self-calibration mode, a gain of the microwave assembly is adjusted according to temperature data of a temperature monitoring module, and is compared with a reference signal inside the microwave assembly, so that the self-calibration of the microwave assembly is realized. Under the transmission mode, a radar signal is received in the microwave assembly through a receiving-transmitting antenna, and is transmitted to radar after being amplified through the microwave assembly. The equipment is radar active calibration equipment with convenience in outdoor work, stable property, high integration density and high precision.
