Noncoherent distance measurement/time synchronism system of cluster link two-way asynchronous communication channel

The invention relates to a symmetrical noncoherent distance measurement / time synchronism system of a cluster link two-way asynchronous communication channel, belonging to the autonomous technical field of aviation data links, radio navigation and aircrafts. By the invention, a symmetrical noncoherent distance measurement / time synchronism method and a system framework can be realized on a DSP (Digital Signal Processor) of a circuit board and an FPGA (Field Programmable Gate Array). Based on the two-way asynchronous communication link between cluster link member nodes, the noncoherent distance measurement / time synchronism system provides a noncoherent spread spectrum distance measurement principle of a two-way asynchronous communication frame under a comprehensive channel system, constructs a noncoherent spread spectrum distance measurement algorithm structure of the air fleet link two-way asynchronous communication frame in a uniform form by adopting a communication frame based on CCSDS Proximity-1 version-3 and provides two algorithms of base line measurement and time synchronism measurement control: an interprocessor time synchronism recursive algorithm and a Doppler integral compensation algorithm. The invention overcomes the defects of the traditional coherent transferring distance measurement and the two-way synchronous noncoherent distance measurement and provides a distance measurement scheme, in which both parts of the two-way asynchronous communication distance measurement can equally acquire a measurement result.
