摘　　要：星基广播式自动相关监视(ADS-B)是实现广域范围内航空器监视的重要技术手段。为解决星基ADS-B系统存在的虚假目标干扰问题,提出一种基于多普勒频移改变量的单星航空器位置验证方法。建立星基ADS-B验证系统模型,理论分析给出空天链路多普勒频移改变量的计算方法,并采用柯尔莫哥洛夫-斯米尔诺夫(k-s)检验方法识别虚假ADS-B消息,最后,通过计算机仿真验证所提方法的正确性和有效性。仿真结果表明:所提方法的检测概率达到97.75%以上,漏警概率低于4.50%;此外,所提方法只需单颗低轨道卫星进行监视,并且对航空器和卫星的定位误差不敏感。Satellite-based automatic dependent surveillance-broadcast(ADS-B)is an important technology for wide-area aircraft surveillance.To solve the problem of false target interference existing in the satellite-based ADS-B system,a position verification method with one satellite based on Doppler shift change was proposed.First,the system model of satellite-based ADS-B was presented.Then,the formula for the Doppler shift change of aerospace link was theoretically provided.Furthermore,the Kolmogorov-Smirnoff(k-s)test was used to verify the authenticity of the ADS-B position message.Finally,the correctness and effectiveness of the proposed scheme were verified by computer simulation.The simulation results show that the probability of detection of the proposed method is more than 97.75%,and the false dismissal probability is less than 4.50%.In addition,only one low-orbit satellite is required for monitoring,and it is not sensitive to positioning errors of aircraft and satellites.
