摘 要：ADS-B，中文名称为广播式自动相关监视，即是飞行器自主广播包含了位置等信息的报文给用户，因此可利用该信息作为监视飞行器的前提是报文信息可靠可信，可见 ADS-B 系统作为独立监视手段存在脆弱性。在考虑 ADS-B 作为独立监视系统的前提下，现提出卡尔曼滤波跟踪航迹预测法和到达时间差法这两种方法，利用 ADS-B 广播的报文信息来进行目标（飞行器）位置真伪的判别，以此提高航空交通管制系统对 ADS-B 报文的信任度，有利于 ADS-B 作为新一代监视系统的广泛应用。

Abstract: ADS-B, the chinese name is broadcast automatic correlation monitoring, that is, the aerocraft autonomously broadcasts a message containing location and other information to the user, therefore, the premise of using this information to monitor aircraft is the message information is reliable, it is clear that ADS-B system is vulnerable as an independent monitoring means. On the premise of considering ADS-B as an independent monitoring system, two methods, Kalman filter tracking track prediction method and arrival time difference method, are proposed to distinguish the authenticity of target (aircraft) position by using ADS-B broadcast message information, so as to improve the air traffic control (ATC) trust in ADS-B information, it is conducive to the wide application of ADS-B as a new generation monitoring system.
Keywords: ADS-B; deceptive jamming; Kalman filter; arrival time difference
