Doppler Position Location: Single Observation Point Feasibility Regions

A novel position location technique that requires a reduced number of scattered observation signals is presented in this paper. This technique infers the mobile’s location based on measurements of angle of arrival (AOA), path length obtainable by time of arrival (ToA) measurements and Doppler Shifted Frequency (DSF). Based upon the principle of same Doppler collinearity, the proposed methodology describes feasible locating regions for scatterers which are collinear with the transmitter. The novelty and advantage of the proposed technique makes it reliable and efficient from an optimality perspective since the location of the mobile is estimated using a single base station in a non-cooperative wireless networking scenario. Therefore, the main contribution is the development of a parametric model capable to provide a feasibility location region in non cooperative scenarios.
