摘　　要：分析了ADS-B机载无线信号特征与通信原理,利用脉冲幅度测向技术,采用四通道幅度单脉冲测向体制,在单一地面站里实现对同一目标的融合监视。通过对系统量化误差、接收机之间增益不平衡引起的误差、接收机引起的测角误差进行分析,同时对接收机噪声基底、四通道接收机和天线方向图进行测向校正,完善软硬件技术性能指标,使地面站作用距离不低于380km,测向的精度不低于5°,同时通过幅度-距离关联的信号距离验证技术,不仅保证地面站监视覆盖的作用距离,而且提高了ADS-B虚假目标的识别率。该技术方法与现有ADS-B监视体制兼容,工程技术容易实现,是一种低成本的ADS-B虚假目标识别技术解决方案。Based on the analysis of the characteristics and communication principle of ADS-B airborne wireless signal,the fused monitoring of the same target is realized in a single ground station by using measurement technique of the pulse amplitude and measurement direction of the four-channel single pulse amplitude.Through the analysis of system quantization error,gain imbalance between receivers,angle measurement error caused by receiver,and measurement direction correction of receiver noise base,four-channel receiver and antenna pattern,the technical performance index of software and hardware is improved,so that the action distance of ground station is not less than 380km,precision about direction of measurement is not less than 5°.This technology method is compatible with the existing ADS-B monitoring system,and it is easy to be realized by the engineering technology,so it is a low cost ADS-B false target identification technology solution.
