1. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival
University essay from Linköpings universitet/ReglerteknikAbstract : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. READ MORE
