摘要：
由于高机动性和易于部署的优势，无人机（UAV）被广泛应用于军事和民用领域。为加强无人机的飞行监视并保障空域安全，无人机可装备广播式自动相关监视（ADS-B）系统，该系统周期性地向其他飞机和地面站（GS）发送飞行信息。然而，由于信道容量资源有限，装备ADS-B的无人机会导致无人机与民用飞机（CA）之间产生干扰，进而影响地面站接收信息的准确性。具体而言，信道容量主要受飞机密度和ADS-B发射功率影响。因此，本研究基于三维泊松点过程，利用随机几何理论构建无人机与民用飞机共存模型，并分析ADS-B监视系统的干扰性能。仿真结果揭示了发射功率、密度、阈值和路径损耗对ADS-B监视系统性能的影响。此外，本文还给出了无人机与民用飞机安全共存的建议发射功率和密度。
英文摘要：
Due to the advantages of high mobility and easy deployment, unmanned aerial vehicles (UAVs) are widely applied in both military and civilian fields. In order to strengthen the flight surveillance of UAVs and guarantee the airspace safety, UAVs can be equipped with the automatic dependent surveillance-broadcast (ADS-B) system, which periodically sends flight information to other aircrafts and ground stations (GSs). However, due to the limited resource of channel capacity, UAVs equipped with ADS-B results in the interference between UAVs and civil aircrafts (CAs), which further impacts the accuracy of received information at GSs. In detail, the channel capacity is mainly affected by the density of aircrafts and the transmitting power of ADS-B. Hence, based on the three-dimensional poisson point process, this work leverages the stochastic geometry theory to build a model of the coexistence of UAVs and CAs and analyze the interference performance of ADS-B monitoring system. From simulation results, we reveal the effects of transmitting power, density, threshold and pathloss on the performance of the ADS-B monitoring system. Besides, we provide the suggested transmitting power and density for the safe coexistence of UAVs and CAs.
