Presentation title: The technique of passive positioning based on vector hydrophones
Summary of the presentation: Direction-of-arrivals (DOAs) estimations have received considerable interests, with most of the existing techniques still relying on scaler hydrophones. One requiring further research is the vector-based positioning technique. Based on the vector-based DOA, this paper investigates poisoning and tracking techniques using vector hydrophones and discusses the observability of motion parameters of moving targets with only the azimuth information of the targets known. The interference pattern of the waveguide field is stable, dependent on several factors including sound speed profiles and source and receiver depths. This paper develops an algorithm to estimate the motion parameters of moving targets using the vector waveguide invariant associated with the inference pattern. Simulations and experiments validate the proposed algorithm.
