摘要

本文结合国内某无线电测向站附近高压输电线路建设，对其附近的无线电测向系统的测向精度进行了跟踪测量，分析、比较了高压输电线路建设前后测向误差的变化，还进行了同场地条件下不同体制测向设备的测向精度比较，验证了理论分析结论.

Abstract

This article researches the radio interference (RI) from the tower scattering of high-voltage power transmission line (HVPTL) to radio direction finding (DF) system.The theoretical simulation is verified by numerical analysis on the measured data.Two HVPTLs nearby a DF station were constructed.From the very beginning we started series tests based on the selected sites around the station.The analyzing and comparison of the test data shows that there is impact of the HVPTL to radio DF

the accuracy of the DF with spatial spectrum estimation is better than the one with correlative interferometer

which improved 1 and 0.5 in corresponding frequency band.
