Radar Data Optical Transmission Solution

1 Overview

In current air traffic control radar applications, synchronous serial transmission is increasingly used. The traditional approach transmits 9600bps asynchronous serial data via PCM equipment. Our company has long focused on military and civil aviation applications and has proposed a radar data optical transmission solution, providing multiple dedicated radar data interfaces for radar data transmission. This solution supports synchronous and asynchronous serial transmission, with a maximum of 128kbps in synchronous mode and 38.4kbps in asynchronous mode.

2 System Design

This solution adopts the SDH optical transmission scheme, supporting point-to-point or point-to-multipoint networking. A typical point-to-multipoint networking diagram is shown below.

Requirement description:

(1). There are 2 remote sites for radar data access in this project, requiring 12 and 4 radar data access channels respectively;

(2). The central site needs to provide 40 radar data interfaces, of which 16 correspond to the radar data servers for the two remote sites' landing access, and the remaining 24 are reserved for future remote site access.

Solution description:

(1) The remote radar optical transmission equipment adopts our MUX180 device, with a single device supporting up to 68 radar data interfaces;

(2) The radar-side optical transmission equipment MUX180 uplinks to the central site via a 155M optical interface;

(3) The radar monitoring center aggregates the remote radar data interface services through the MUX180 equipment and lands them into the radar monitoring server;

(4) For application scenarios with a relatively small number of radars, point-to-point fiber interconnection can also be used for transmission. A typical application diagram is shown below.
