According to interface requirement of certain airborne station, a detection controller project based on MCU is designed through adding frequency code circuit, display circuit, and buffer circuit. The hardware block diagram and principle are introduced. The main software and data processing flow chart is programmed. Application result indicates that the detection controller can control the airborne station, display status messages, and output test signal. The detection controller has many characteristics, such as broad application and strong anti-jamming.
