Adaptive DOA Estimation Using Subspace Method for Underwater Applications
G Vinodha, Pranishaa R Prakash, C. Ashok · 2018
In this paper, the incoming signal is processed from a given source by employing an array of hydrophones and estimating the signal parameters. This work is concerned with estimating and projecting the motion of the signal parameters like Direction of Arrivals (DOA) of multiple emitters using ESPRIT method in underwater scenario. The algorithm is employed in an adaptive manner as the targets that are considered are in continuous motion. For targets that move with constant accelerations, their motion is projected based on the time series. The robustness of this approach is validated with several numerical simulation results. This helps us to develop a system that will yield the most accurate results.
