摘　　要：随着新兴多旋翼无人机平台的快速发展,应用领域日益广阔。从系留多旋翼无人机平台的特点出发,分析比幅比相两种体制的测向工作原理及误差来源,提出一种基于系留多旋翼无人机的联合测向技术。通过一种天线均匀圆形布阵形式实现了360°比幅比相联合测向,系统测向解模糊能力和测向精度均得到明显的提高。仿真分析和试验验证表明,该联合测向技术可实现对辐射源信号的幅相特征采集、提取和分析,并灵活配置比相干涉仪基线长度,提升系统比相测向解模糊能力和测向精度。该技术具有灵敏度高,测向范围广和测向精度高等特点,工程应用价值高。With the rapid development of the emerging multi-rotor UAV platform,the application field is expanding day by day.Based on the characteristics of the tethered multi-rotor UAV platform,the working principle and error source of the two systems of the amplitude-phase comparison direction finding methods are analyzed,and a joint direction finding is put forward based on the system-retained UAV.Through an antenna uniform round array form to achieve a 360 degree amplitude-phase comparison direction finding of the joint measurement direction,the system directional solution fuzzy ability and measurement accuracy are significantly improved.The simulation analysis and test verification show that the acquisition could be realized by the joint direction finding,and also extraction and analysis of the amplitude-phase feature of the radiation source signal.And the baseline length of the phase interferometer is configured flexibly,which improves the system?s comparison-to-phase solution fuzzy capability and measurement accuracy.The technology has the characteristics of high sensitivity,wide range of direction measurement and high accuracy of direction measurement,and high value of engineering application.
