中文摘要: 同航管雷达相比,广播式自动相关监视(ADS-B)系统具有精度高、成本低的特点,将是通用航空目标的主要监视手段。ADS-B由卫星定位系统和数据链路系统两个关键部分组成。由于通航目标具有低空飞行的特点,这两者极易受到地面射频干扰及多径干扰等干扰的影响。本项目将研究用于通用航空的ADS-B抗干扰技术。主要研究内容包括如下:ADS-B卫星定位系统抗干扰技术、基于自主完好性监测(RAIM)的ADS-B定位信号增强技术、ADS-B数据链路中地面设备抗干扰技术、ADS-B数据链路中机载设备抗干扰技术,并在此基础上开发抗干扰技术验证平台。有关成果可以提高通用航空中ADS-B系统的抗干扰能力,也可推广到运输航空和军用航空系统中,具有广泛的学术意义和实用价值。

英文摘要: Compared with surveillance Radar, ADS-B(Automatic Dependent Surveillance-Broadcast) system has higher precision and lower cost, which will be the main surveillance technology for general aviation. Satellite positioning system and data link are the two key integral parts.As the low flying height, ground RF(Radia Frequency) interference and multipath interference have serious impact on satellite positioning system and data link. This project is to provide interference suppression algorithms for ADS-B system in general aviation. The main research contents include: interference suppression for satellite positioning system in ADS-B system, signal enhancement for positioning system based on RAIM(Receiver Autonomous Integrity Monitoring), interference suppression for ground equipment of date link in ADS-B system, interference suppression for airborne equipment of data link in ADS-B system, system-level interference suppression for ADS-B system in gengeral aviation and verification platform of interference suppression algorithms. Relevant outcomes have a wide range of scientific and practical value, which can improve anti-interference ability of the general aviation ADS-B system, and can be extended to transport aviation and military aviation system.
