Abstract
This report discusses the results of microwave radio direction finding (DF) experiments carried out using the horizontal linear antenna array of an experimental N-channel radar system. The main purpose of these experiments was to investigate the effect of the maritime propagation environment on DF performance for signal paths up to and beyond the radio horizon. As part of this investigation, a comprehensive error analysis was carried out to identify and quantify the most significant sources of bearing error. These sources were mainly instrumental in error although significant errors could also be produced as a result of destructive interference between the direct signal and the ocean surface reflected signal. Based on the error analysis, it was concluded that in a maritime environment, microwave direction finding accuracies of significantly better than one degree RMS are possible, even for paths several kilometers over the radio.
