| With the continuous development of air traffic control,radar control has basically covered the whole country.In recent years,with the renewal and transformation of radar equipment by regional air traffic control sub-stations,more than twenty INDRA secondary radars have been put into use nationwide.Monitoring of radar signals has become an important part of air traffic control technical support.It is also obvious to analyze and discuss the data format of radar signals.Especially important.As the basis of radar control,it is particularly important for radar to eliminate faults in time and ensure its normal,safe and stable work.There are many kinds of radar equipment and different manufacturers.The monitoring systems of each radar are independent of each other,and the fault information can not be transmitted in real time,which is not conducive to the centralized monitoring of multi-radar systems.Based on this problem,we need to develop an INDRA radar monitoring and management system which can access the existing centralized monitoring system and provide INDRA radar status in real time,and display radar status on the office computer.The design of radar monitoring and management system will synthesize the original data of radar monitoring system,and only reflect the fault of radar system,so as to improve the security level of air traffic control radar.The main research work of this paper includes:(1)This paper introduces the concept and related technology of air traffic control secondary radar,and expounds the technical principle of secondary radar data output and composition.(2)Research and analysis of radar data processing methods,including ASTERIX,HDLC protocol,secondary radar transponder code re-allocation method,secondary radar target update cycle calculation method,etc.(3)The overall architecture design and function design of INDRA radar monitoring and management system are completed,and the simulation test is carried out.The innovations of the paper include:(1)The data processing method suitable for INDRA radar monitoring is analyzed,and the suitable data acquisition scheme and secondary development scheme are pointed out.(2)The main functions of INDRA radar monitoring and management system are designed and implemented,including multi-radar data acquisition,radar interface display of monitoring and management terminal,etc.The simulation results show that the main functions of the system are basically completed,and the system is suitable for multi-radar ATC application environment. |
