【摘要】：广播式自动相关监视（ADS-B）是国际民航组织大力发展的一种空管监视技术，在空管系统中使用该技术可以大大提高空中监视效率，减少空中交通管理的费用和成本。目前，世界各国纷纷响应国际民航组织的号召，大力推广和发展ADS-B系统，澳大利亚、美国、欧洲已经开始在空管监视系统中使用ADS-B设备。ADS-B较成熟的数据链路有三种：UAT数据链路、Mode S1090MHz ES数据链路和VDL MODE4数据链路，国内正大力发展1090MHz ES数据链路，该链路在国内已经有比较成熟的地面接收设备，本文详细介绍了一种基于1090MHzES数据链路的ADS-B目标模拟器的设计，该模拟器能模拟出三类飞行状态的多个目标，这三类飞行状态包括：水平匀速直线飞行，匀加速上升飞行和匀减速下降飞行。本设计最多能够模拟200个ADS-B目标，可以很好的检测ADS-B设备的接收性能。模拟器主要由控制系统和发射系统组成，其中发射系统由射频前端发模块和发射主板组成，发射主板采用ARM+FPGA的硬件架构，作者主要负责ARM模块的设计和控制系统的设计。论文的主要内容包括： 1、按照ADS-B设备性能指标要求，分析模拟器的功能要求，并对模拟器的总体进行了设计。 2、控制系统的设计，该部分探讨了控制系统和发射系统的协议、介绍了三类目标数据的模拟，另外详细的描述了各类目标的消息编码处理和控系统数据发送设计，最后描述了控制系统人机交互界面的设计。 3、发射系统的设计，发射系统主要由发射主板和射频前端组成，发射系统主板采用ARM+FPGA硬件结构，该部分主要偏重介绍ARM模块的设计，主要包括：ARM和FPGA接口和通信协议的设计，μC/OS-Ⅱ的移植，多目标ADS-B消息的随机发送，ADS-B消息的更新等。 4、模拟系统功能测试和分析，包括各类目标的测试，并对这些测试结果进行了分析。
[Abstract]:Broadcast automatic correlation Surveillance (ADS-B) is a kind of air traffic control surveillance technology developed by ICAO. The application of ADS-B in air traffic control system can greatly improve the efficiency of air surveillance. Reduce the cost and cost of air traffic management. At present, countries around the world have responded to the call of the International Civil Aviation Organization, vigorously promote and develop the ADS-B system, Australia, the United States. Europe has begun to use ADS-B devices. ADS-B 's more mature data links in ATC surveillance systems. There are three types of: UAT data links. Mode S1090MHz es data link and VDL MODE4 data link, 1090MHz es data link is being developed in our country. In this paper, a ADS-B target simulator based on 1090MHz data link is introduced in detail. The simulator can simulate multiple targets in three flight states, which include horizontal and uniform linear flight. This design can simulate up to 200 ADS-B targets. The simulator is mainly composed of control system and transmitting system, in which the transmitter system is composed of RF front-end transmitter module and transmitter motherboard. The launch motherboard adopts the hardware structure of ARM FPGA. The author is mainly responsible for the design of the ARM module and the design of the control system. The main contents of this paper are as follows: 1. According to the performance requirements of ADS-B equipment, the functional requirements of the simulator are analyzed, and the overall design of the simulator is carried out. 2, the design of control system, this part discusses the protocol of control system and launch system, and introduces the simulation of three kinds of target data. In addition, the message coding processing and data sending design of the control system are described in detail. Finally, the design of the human-computer interface of the control system is described. 3. The design of the launch system, which is mainly composed of the main board and the RF front end. The main board of the launch system adopts the ARM FPGA hardware structure. This part mainly introduces the design of the ARM module. It mainly includes the design of the interface and communication protocol between the: arm and FPGA, the transplant of 渭 C / OS- 鈪，
