摘要:

根据ADS-B 地面站覆盖范围的需要考虑地形遮蔽地球曲率顶空盲区及设备性能等因素计算了ADSB地面站的理论覆盖范围基于ADS-B 数据采用Lambert 投影方法提出了一种凹包生成算法依据实测数据计算不同高度层的ADS-B 覆盖图提出一种ADS-B 连续性计算方法并计算漏点率和连续性等级结果表明该方法能够提供地形遮蔽影响下的理论最大覆盖范围可用于辅助ADS-B地面站的选址决策

关键词: ADS-B, 覆盖范围, Lambert投影方法, 凹包生成算法

Abstract:

According to the factors such as topography, earth curvature, headspace blind zone and equipment performance,theoretical coverage of ADS-B ground station is calculated. Based on ADS-B data, Lambert projection method is used to project the generation algorithm of concave hull. Based on measured data, the coverage of ADS-B under different layers of height is calculated. An ADS-B continuity calculation method is proposed to calculate the leakage rate and continuity level. Results show that the proposed method can provide theoretical maximum coverage under the influence of terrain shelter and can be used to assist ADS-B ground station's location decision.

Key words: ADS-B, coverage, Lambert projection method, generation algorithm of concave hull
