摘要

In order to solve the difficult testing and acquiring the real interlaced signal of the automatic dependent surveillance-broadcast(ADS-B),a synthetic method of multi-target ADS-B signal is proposed.The principle of multi-target generation technology is introduced,according to ADS-B signal feature,design a digital processing method based on multi-target ADS-B intermediate frequency superimposed signal,then simulation analysis and verification were accomplished by numerical experiments.The result showed that the method could generate and simulate the superposition of multi-target signal in the space.The technology could be used to test and verify the performance and function index of the ADS-B equipment,and provide technical support for ADS-B system engineering application.%为解决广播式自动相关监视(automatic dependent surveillance-broadcast,ADS-B)性能和功能指标难以测试、真实交织信号难以获取的问题,提出一种多目标ADS-B信号合成方法.介绍了多目标生成技术的工作原理,依据ADS-B信号特征,设计了一种基于多目标ADS-B中频叠加信号的数字处理方法,并通过数值试验进行仿真分析与验证.仿真结果表明:该方法能很好地产生和模拟空间中多个目标的叠加信号,测试和验证ADS-B设备的性能和功能指标,为ADS-B系统的工程化应用提供技术支持.
