Rotor Effects on L. Band Signals Received by Helicopter Antennas. Part III. Measurements of the Amplitude and Phase Distortions of CW Signals.

Abstract

An experimental study of rotor-blade-induced distortions of L-band signals has been carried out to verify the results of a previous theoretical investigation. These signals were received by helicopter antennas mounted on the cabin roof below the rotor. To verify the theoretical findings, the effects of such distortions on horizontally and vertically polarized incident signals were measured for several directions of incidence. The results of both the theory and experiments are in excellent agreement.
