WebSep 9, 2011 · An algorithm is proposed for passive bearing estimation where the number of sources and their source signals are considered unknown in the presence of noise. An unknown but limited number of targets is assumed to be distributed in bearing (look angle) with unknown bearings and magnitudes. WebApr 11, 2024 · The problem of estimating the azimuth and elevation angle of a sound source using a compact array of hydrophones is addressed. The closed-form representations for several time-difference of arrival (TDOA) based estimators are given, and their accuracies are evaluated using both statistical simulations and in situ tests. Simulations … WebOptimum bearing and range estimators are presented for the planar problem and related to the optimum time delay vector estimator.
