基于距离矩阵的二次雷达S模式询问器代码分配方法研究

摘要

S模式是一项可逐步取代传统A/C模式的二次雷达新技术.S模式雷达使用询问器代码作为与具有共同覆盖区域的相邻雷达进行区分的身份信息.当辖区内S模式雷达的位置关系及共同覆盖区域较复杂时,直接为每部雷达进行询问器代码赋值比较困难.阐述了S模式询问器代码的功能和类别.通过构造距离矩阵研究S模式二次雷达询问器代码的分布特性,提出了一种利用距离矩阵进行询问器代码分配的方法.该方法解决了复杂位置关系下的S模式雷达询问器代码分配较困难的问题,通过华东地区空管S模式雷达系统对该方法的可靠性进行了实例验证.%Mode S is a new kind of technology that can gradually replace the traditional mode A/C of secondary surveillance radar.The mode S radar uses the interrogator code as identity information that distinguishes adjacent radars with common coverage areas.It is difficult to directly assign the interrogator code to each radar when the positional relationship and the common coverage area of the mode S radar in the jurisdiction are complex.This paper describes the functions and categories of mode S interrogator code.The distribution characteristics of the interrogator code of mode S secondary surveillance radar are studied by constructing the distance matrix,and a method of interrogator code assignment using distance matrix.This method solves the problem that mode S radar interrogator code assignments are difficult when the radar positional relationship is complex.The reliability of the proposed method has been validated by using the ATM mode S radar system in East China.
