A four-element direction-finding antenna
Abstract
An HF direction-finding method is described which determines simultaneously the azimuths of two signals. This method employs a four-element antenna and provides coverage over 360 degrees. It was used successfully in seven oceanographic experiments to measure ocean surface currents remotely in a complex multi-signal environment. The method is an integral part of an HF Doppler system that was developed to map currents routinely.
