Abstract
The report discusses the results of VHF radio direction finding (DF) experiments carried out with an experimental linear eight antenna DF system. The main purpose of these experiments was to investigate the effect of the environment, in particular multipath propagation, on DF performance. A theoretical analysis of all known error mechanisms has also been carried out in order to better understand the measured results. This includes temporal noise, equipment errors, mutual coupling, and multipath. The analysis of multipath also includes the development of new models to predict statistical effects. The results of this investigation indicate that multipath effects are complex and may create difficulties in modern systems if improved accuracy is an objective. Further measurements will be required to verify these preliminary findings.
