摘　　要：针对通用航空飞行活动的安全监视问题,合理的广播式自动相关监视(Automatic dependent surveillance‑broadcast,ADS‑B)地面站选址规划能够提高空域的监视范围,基于网格划分分析ADS‑B地面站对真实高度的监视信号覆盖范围并进行选址分析。考虑地球曲率和地形遮蔽对信号传播距离的影响,采用数字地理高程数据建立地理模型,将空域网格化处理,用Xdraw算法计算网格覆盖性,确定ADS‑B地面站对真实高度的最大理论覆盖范围,构建地面站最大覆盖模型进行空间规划布局。最后,对ADS‑B地面站信号覆盖情况进行仿真,并以湖北省为例,计算出满足该区域覆盖需求的地面站布局。为实际工作中的地面站布局规划提供了依据。Aiming at the security monitoring problem of general aviation flight activities,a reasonable automatic dependent surveillance-broadcast(ADS‑B)ground station location planning can improve the airspace surveillance scope.This paper proposes a surveillance signal coverage analysis method of the true height and its location analysis of ADS‑B ground station based on grid division.First,considering the influence of earth curvature and terrain shading on the signal propagation distance,we establish the geographic model by the digital elevation model(DEM),and divide the airspace into grids.Second,the grid coverage is calculated by the Xdraw algorithm,and the maximum theoretical coverage of ADS-B ground station at the true height is determined.Third,the maximum coverage model of the ground station is constructed for spatial planning and layout.Finally,the signal coverage of ADS‑B ground station is simulated as Hubei Province is taken as an example.The layout of ground stations that meet the coverage requirements of this area is calculated.The results demonstrate that the proposed method can provide a foundation the layout planning of ground stations in practice.
