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.
