Abstract

Direction finding devices, such as phase interferometers, when operating over a rough surface (such as the sea ocean or terrain) sustain inferior performance. This performance degradation is due to the so called multipath interference from reflections by the rough surface. In this thesis we analyze multipath effects on linear array phase interferometers. Based on parametric models for this multipath interference we derive recursive signal processing algorithms for estimating the angle of arrival of electromagnetic plane waves. Comparison with other existing algorithms is also provided.
