Design and Implementation of HDLC Synchronous Serial Port for ATC Radar

The ATC radar data network uses the HDLC protocol to transmit target data, and the ATC radar and ADS-B equipment must be able to support the HDLC protocol and provide multiple synchronized serial ports for outputting radar data.

Introduction to HDLC Protocol

HDLC protocol, sometimes known as SDLC protocol, is a link layer protocol widely used in industry communications. The HDLC protocol specification is referred to the ISO / IEC 13239 standard document.

The Selection and Configuration of Synchronization Clock for HDLC Protocol

Synchronous HDLC serial communication, different from ordinary asynchronous communication, the clock signal plays an important role, only the sender and receiver use the same clock, can achieve highly reliable data transmission.

Impact of ADS-B on the ATC radar data network

Due to the advantages of low station construction cost and high data refresh rate, ADS-B receivers have been applied in large scale in ATC system.
