Multi-channel irregular radar data real-time analysis and concentrated-transmission-receiving card and communication method thereof

Abstract

The invention discloses a multi-channel irregular radar data real-time analysis and concentrated-transmission-receiving card and a communication method thereof, relating to the technical field of processing of radar data in an air traffic control (ATC) system. According to the invention, a DSP (Digital Signal Processor) and an FPGA (Field Programmable Gate Array) are used as cores based on a PCI (Programmable Communications Interface), data communication with a PC application program is realized through the PCI; and especially, the 8-channel FPGA for receiving and transmitting synchronous, asynchronous and full duplex data, the DSP for analyzing various types of radar data protocols is realized, and a drive program and an application program of a PC are realized. According to the invention, the connection of the air traffic control system to a radar signal is optimized, system access of various kinds of radar signals is met, capacity is conveniently expanded, and various types of radar data can be set and forwarded.

Description

technical field [0001] The invention relates to the technical field of radar data processing in an air traffic control system ATC, in particular to a multi-channel special-shaped radar data real-time analysis centralized transceiver card and a communication method thereof. Background technique [0002] In the domestic air traffic control system ATC in the past, the receiving and processing of radar data usually adopts multi-channel serial receiving cards of foreign companies and external synchronous radar receiving equipment. Such a system has complex structure, high bit error rate of signals, and because the purchased equipment is limited by national conditions and other factors, the imported equipment has incomplete functions and low efficiency, which cannot meet the needs of a modern air traffic control system. Therefore, a multi-channel special-shaped radar data real-time analysis centralized transceiver card is designed to meet the system access to various types of rada...
