Abstract : Helicopters are electrically charged during their flight. The electric charge generates an electric field in the helicopter's vicinity which can be measured. By such electric field measurements, the detection and localization of flying helicopters is possible in principle. Numerous systematical investigations have been performed in connection with different types of helicopters flying over ground-based electric field sensors. Supplementary electric field sensors were telemetric guided in the vicinity of hovering helicopters. The experimental results were compared with theoretical computations about electric field distributions of electric charged helicopters hovering near trees and buildings. (Author)
