摘　　要：为了使空管监视设备的选址更加科学高效,探讨了一种减小选址范围的分析方法。首先,结合地形遮蔽因素和设备垂直辐射特性对设备的覆盖性能进行分析,得到空间内任意一点设备可视的条件,在此基础上提出一种反向视域分析方法,该方法在保证空域覆盖要求的条件下得到选址范围的边界,以及不同位置设置站点所需的天线高度。然后,为避免定位点和航路受到设备顶空盲区的影响,推导出定位点的不合理选址半径和航路不合理选址宽度的计算方法,并在选址范围内剔除顶空盲区影响下不合理的选址区域。最后,对于设备选址其他影响因素造成的不合理选址区域也进行了类似分析,最终可确定一个小范围的选址区域。In order to make site selection for air traffic and efficient, a method for diminishing the range of siting control（ATC） surveillance facility more scientific is discussed. Firstly, combining with the terrain factors and the antenna vertical radiation characteristics, the coverage performance of the surveillance facility is analyzed, and the visibility condition for any point is obtained. On this basis, a reverse line of sight analy- sis method is proposed, which is used to get site selection area boundaries and the required antenna height in different sites under the specific airspace coverage requirement. Then, in order to avoid the air fix point and the route being affected by the antenna overhead skip zone, the calculation methods of the air fix point unsat- isfactory siting radius and the route unsatisfactory siting width are deduced. The unsatisfactory site selection area is ruled out. Finally, other factors causing the unsatisfactory siting area are analyzed in the similar way. A more precise site selection area can be determined eventually.
