Abstract

This work considers the problem of target localization in a 3-D space, using coupled measurements of angle of arrival (AoA) and received signal strength (RSS). By applying the transformation from Cartesian to spherical coordinates and by taking advantage of the available AoA observations, we establish novel relationships between the measurements and the unknown target location. From these relationships, we derive a simple closed-form solution estimator. Simulation results validate the remarkable performance of the proposed estimator, both in terms of estimation accuracy and execution time.
