Problems solved by technology

Early surface surveillance radars could only display processed ground targets on the screen. As for whether the target was an aircraft or a vehicle, controllers could only judge based on the size of the displayed target and their own experience.

Abstract

The invention relates to a high-data-rate transmission system of a scene-monitoring air traffic control radar. The system comprises an optical fiber transmission system and a kilomega network system wherein the optical fiber transmission system comprises a digital receiver, an optical amplifier, an optical acquiring card and a computer; the kilomega network system comprises a digital receiver, an exchanger and a computer; the optical fiber transmission system is used for transmitting an original echo data signal of the radar unidirectionally; the kilomega network system is used for directionally transmitting data signals excluding the original echo data signal of the radar. The system disclosed by the invention adopts a method that optical fibers are combined with a kilomega network and is also matched with an optical power divider having an amplification function, a four-way high-speed optical acquiring card and a computer having a high-speed storage function. Effective high-data-rate transmission is guaranteed, and the reliability of the system is improved as well due to an interaction mode of mutual duplication of the computers.

Description

technical field [0001] The invention relates to a transmission system, in particular to a transmission system of a scene monitoring air traffic control radar capable of ensuring high data rate transmission. Background technique [0002] Surface surveillance radar is a kind of primary radar, which is often used by some large airports to monitor airport traffic. Early surface surveillance radars could only display processed ground targets on the screen. As for whether the target was an aircraft or a vehicle, controllers could only judge based on the size of the displayed target and their own experience. With the development of computer technology, data processors appear in surface surveillance radars, which can perform data fusion and other related processing on their data and external data such as flight data processors and secondary radar output data, so as to hang aircraft signs. This not only enables controllers to distinguish between aircraft and vehicles, but also to id...
