机载ADS-B技术现状与发展趋势

随着广播式自动相关监视( ADS-B )技术的发展与广泛应用,国外涌现出许多 ADS-B 设备研制商,开发出多种应用于不同平台、具有不同功能构型的 ADS灢B 产品。从搭载平台与功能构型两个视角出发,对国内外机载 ADS-B 产品进行分类;分析航线飞机、通航飞机以及无人机载 ADS灢B 产品的功能与技术特点,并针对当前 ADS-B 系统面临航空器监视应用开发、安全性、密集干扰环境下接收增强、1090ES 链路扩容等难点问题,分析讨论技术途径并提出发展建议。

A Survey on Airborne ADS-B Technology and Its Development Trend

With the development and wide application of automatic dependent surveillance-broadcast (ADS-B) technology, there have been emerging many ADS-B manufacturers who have developed a large number of ADS related products with versatile configurations for different airborne platforms. This paper firstly categorizes the diverse ADS-B products with respect to configuration and intended platform, and then, analyzes the functional and technical characteristics of the ADS-B products designed for airlines, general aviation, and unmanned aircraft system (UAS). Finally, this paper analyzes and discusses the countermeasures to the challenging problems of ADS-B system including information security, enhanced reception in dense jamming environment, as well as 1090MHz channel capacity improvement.
