Prony has been around for centuries (first used to predict tides in the 
18th century, as I recall)

MUSIC - Multiple Signal Classification - look for the papers by 
Schmidt.. IEEE Trans on Ant and Prop March 1986
ESPRIT - Estimation of signal parameters using Rotational Invariant 
Technique... I think Roy and Kailath are the authors of most of the 
early papers.  Perhaps MILCOM conference papers?
