Abstract

Source localization in a waveguide involves a multi-dimensional search procedure. In this paper we propose a new algorithm, in which the search in the depth direction is replaced by polynomial rooting. The proposed algorithm decreases the search dimension to one for a 2D localization problem (range and depth) and to two for a 3D one (range, depth, and direction-of arrival (DOA)), independently of the number of sources. Consequently, the presented algorithm requires significantly less computation.
