Abstract :
Conditions for unique localization of radiating sources by passive sensor arrays are presented. Unlike previous analyses, the case wherein the signals are constrained to certain loci in the complex plane is addressed. The conditions specify the maximum number of sources that can be uniquely localized by a general array satisfying some mild geometrical constraints. This number exceeds substantially the corresponding number for the unconstrained-signals case
