Interference Localisation Trials Using Adaptive Antenna Arrays

M. Trinkle and D.A. Gray

Abstract:	This paper presents the results of an interference localisation trial using an experimental adaptive antenna array currently under development. The prototype adaptive antenna array was driven through a field of RF transmitters and the direction of arrival (DOA) of multiple RF signals at various positions of the vehicle were estimated. From these DOA measurements the transmitter locations were estimated by triangulation. The adaptive antenna array was also used to reject the interfering RF signal in real time to allow the accurate GPS position of the vehicle to be determined in the presence of strong interferences.
