摘要
近年来,无线电干扰严重危害民航通导设备的安全运行。针对“最后一公里”下民航无线电监测系统定位干扰源效率不高的问题,通过SDK开发将测向数据融入无人机下行遥测数据帧,并在移动地面站以示向线交汇形式估计目标干扰源位置,提高了监测任务的便捷性。通过仿真分析典型定位模糊区性能指标,为航线规划提供了减少定位误差的理论依据。最终通过实际测试,得出空中监测观测点在60°示向线交汇的归一化值,比相邻示向线交汇值与交叉定位解算值定位精度更高的结论,可进一步提升空中无线电监测定位效率。
In recent years,radio interference has seriously endangered the safe operation of civil aviation communication equipment.This paper addressed the problem of inefficiency in locating interference sources in the"last mile"civil aviation radio monitoring system,incorporated directional data into UAV downlink telemetry data frames through SDK development,and estimated the location of target interference sources in the form of intersection of directional lines at mobile ground stations to improve the convenience of monitoring tasks.In addition,the performance index of typical positioning ambiguity zone was analyzed by simulation,which provides a theoretical basis for route planning to reduce positioning errors.Finally,through practical tests,it is concluded that the normalized value of airborne monitoring observation points in the intersection of the 60°shear lines is more accurate than the intersection of adjacent shear lines and the cross-location solution value,which can further improve the efficiency of airborne radio monitoring positioning.
