Abstract

A new computationally efficient path-following algorithm is presented for source localization that uses a uniform linear sensor array. An algebraic relation is demonstrated between the bearing of a source under a plane wave assumption and the actual source bearing and range. This relation can be used as a path to follow to the peak of the 2-D MUSIC spectrum. As a result, in the case of an array that has m sensors with n sources, this new algorithm can reduce the number of searches to n independent 1-D searches following the known algebraic path
