Location estimation from a single mobile rotated antenna

Abstract

We propose a method on location estimation of stationary emitters using power measurements from a single antenna. The antenna completes the rotation of one cycle at different positions and from each position, the direction of arrivals (DOAs) of the emitters are estimated. The intersections of the lines of DOAs are then used to estimate the emitters' locations. For multiple emitters, we propose to use three antenna positions to overcome the problem of ambiguity. Simulation results show that the proposed method is effective to estimate the locations of emitters.
