摘　　要：文章介绍了二次雷达与飞行器之间进行信息交换的方法及其应用。首先将二次雷达从基本型A/C模式升级到S模式,再利用S模式的信息交换功能,实现地面发起的信息交换和空中发起的信息交换功能。我们通过对信息交换流程的设计,实现了飞机识别符的获取与确认;通过信息交换实现了相邻地面雷达站之间的S模式协同监视。采用协同监视,降低询问频次,减少二次雷达的异步应答干扰,提高S模式目标监视的可靠性和连续性。This paper introduces the method and application of information exchange between secondary surveillance radar and aircraft.Firstly,the secondary surveillance radar is upgraded from the Mode A/C to Mode S,and then the information exchange function of Mode S is utilized to realize the information exchange initiated by the ground and the air.Through the design of the information exchangc process,we realize the acquisition and confirmation of aircraft identification,and the Mode S Surveillance Co-ordination Function between adjacent ground radar stations.Adopt Mode S Surveillance Co-ordination Function to reduce the interrogation frequency,reduce the asynchronous response interference of secondary surveillance radar,and improve the reliability and continuity of Mode S target monitoring.
