Errors in Lightning direction Finding by Airborne Crossed Loops

Abstract

Analytical and computer approaches are presented for predicting the site errors of airborne crossed loops used for lightning direction-finding. This type of azimuth error is caused by distortion of the incident field due to induced skin currents. Computer code results are presented for a T-39 and a C- 130 aircraft used in flight-testing a commercial crossed-loop system. Another type of bearing error, caused by non-vertical lightning channels, is analyzed for the case where both detector and lightning source are above a conducting ground plane. Also discussed is the 180-degree ambiguity and its resolution by an electric field antenna.
