Ambiguity analysis in source localization with unknown signals

Abstract
A general definition of an ambiguity function, based in the Kullback-Leibler directed divergence between probability densities, is formulated. The ambiguity function summarizes all the geometric aspects of the problem, measuring the difficulty in distinguishing between two different source locations. It is shown that by considering a particular model the classical RADAR ambiguity function is obtained. The use of the definition is illustrated by applying it to several problems, showing that it is a useful tool for the analysis of passive location systems.
