摘　　要：通过对广播式自动相关监视(ADS-B)技术的监视安全性分析,提出了一种基于到达时间差/到达时间和(TDOA/TSOA)的ADS-B系统防欺骗技术。根据TDOA和TSOA等参数求解一个非线性方程组对目标进行三维物理定位,并与地面接收站解析得到的ADS-B信息进行对比分析来实现ADS-B系统防欺骗技术。最后对定位误差公式进行了推导和分析,仿真了地面接收站的几何构型与目标定位精度之间的关系,仿真实验结果验证了该技术的可行性和有效性。Through analyzing the monitor safety of automatic dependent surveillance-broadcast （ADS-B） technology, this paper proposed the ADS-B system anti cheat technology based on TDOA/TSOA. According to obtained TDOA and TSOA parameters the method solved a nonlinear equations to achieve target three-dimensional physical location. Then it compared and analyzed with ADS-B ground station information to achieve ADS-B system anti-spoofing technology. Finally, it derived and analyzed the positioning error formula, and simulated the relationship between the ground station geometric configuration and target location accuracy. Results demonstrate the feasibility and effectiveness of the technology.
