摘要
自动相关监视系统(ADS-B)在未来的民用航空通信、导航及监视中占有重要的地位,在MATLAB环境下进行算法仿真实现ADS-B系统的相关功能,实现了对接收数据的解析处理,初步验证了算法的可行性和正确性。在系统硬件设计过程中摒弃了传统的设计思路,采用软件无线电的设计方法进行ADS-B系统的设计实现,在片上系统和FPGA中处理更多的调制解调和数据处理,提高系统的可重复配置和更改属性,也提高了系统的经济性,有助于ADS-B系统在各类航空器上的应用。
The automatic dependent surveillance-broadcast(ADS-B)plays an important role in the future civil aviation communication,navigation,and surveillance.This paper simulates the ADS-B system in the MATLAB environment to implement ADS-B function as well as parse of the received data,verify the feasibility of the algorithm preliminarily.In the process of system hardware design,the traditional design ideas are abandoned.The design method of ADS-B is implemented by software radio design method.More modulation and demodulation and data processing are processed in the system on chip and FPGA to improve the repeatability of the system.Repeatable configuration and change properties also increases the economics of the system and helps the ADS-B system to be used on all types of aircraft.
