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。
According to the needs of ADS-B ground station coverage, the theoretical coverage of ADSB ground station is calculated considering factors such as terrain shadowing, curvature of the earth, blind spot in the head space and equipment performance. Based on the ADS-B data, the Lambert projection method is used to generate a concave-convex algorithm. Based on the measured data, ADS-B coverage maps are calculated and the ADS-B continuity calculation method is proposed. And continuity level. The results show that this method can provide the theoretical maximum coverage under the influence of terrain shadowing and can be used to assist the location decision of ADS-B ground station.
