Development Of Radar Terminal System In An Airport

The airport radar terminal system is designed based on the principle of secondary radar surveillance,and has an advanced air traffic control system that monitors,guides,and controls aircraft within the detection range.Its main function is to inquire about the designated working mode of the aircraft,and to amplify,demodulate,decode and point track processing of the echo information signal from the airborne transponder to obtain the aircraft’s code,altitude,distance,azimuth and other information,And accurately display in the display device in the terminal of the radar system,and provide important airspace flight parameters to the traffic control center of the inquiring airport.This article discusses in detail the principle of the secondary radar system,the anti-jamming processing method of the secondary radar system,the high-reliability and high-performance secondary radar system architecture,and the detailed process of software and hardware design.Firstly,this paper introduces the basic structure and principle of secondary radar antenna of airport radar terminal system and antenna feeder subsystem,and discusses the detection and tracking principle of radar target in detail.Combined with the characteristics of secondary radar antenna function,through the analysis of current general requirements of radar terminal system,the main aspects of signal transmission and reception of secondary radar are clarified Working parameters.Based on the above theory,the terminal system of airport radar is constructed,which takes the secondary radar system as the design core.Secondly,this paper describes the system architecture of the radar system,including the antenna feeder subsystem,radar site construction,radar software system design,etc.,and focuses on the realization of the secondary radar inquiry extension,switching extension,and radar monitoring / local monitoring software of the antenna feeder subsystem.This paper focuses on the analysis of the structure and principle of the airport terminal radar system,the design of the working process of the secondary radar,and the construction of the software and hardware of the radar system.The main design work includes the signal transmission and signal reception process of the radar,so that the terminal system can carry out high-resolution and high-resolution for the distance and direction of the detected aircraft.The research and development of this system is of great importance to the design and application of the domestic rapidly developing airport terminal radar system.
