The receiver is the core of distance measuring equipment(DME), and the main functions need to realize include receiving the Gauss shaped interrogation pulse from the aircraft, in order to measure the distance from the aircraft. The dissertation mainly studies the DME receiver technology, using digital and modular design method, dividing it into different modules according to the function, and dividing the design into digital front-end and signal processing section. Among them, digital front-end is composed of RF processing module, semi amplitude demodulation module; the back-end signal processing is composed of coding and decoding module, Morse identification pulse generating module, transmitting pulse priority control module. Testing shows the circuit operates with stable performance and high reliability.
