Abstract

A heuristic solver such as particle swarm optimization (PSO) is used for single snapshot direction of arrival (DOA) estimation of a set of signals impinging on a uniform linear array (ULA). A performance analysis for infinite signal-to-noise ratio (SNR) shows the validity of this approach and an example using signal and ULA parameters from a more realistic DOA problem is also included.
