Abstract
A module conversion method for resolving phase ambiguity and consequently e stimating the direction of arrival (DOA) of an electromagnetic wave inciden t on a multielement interferometer with nonuniform spacings is presented. T he technique involves a step-by-step reduction of the number of ambiguities in the measured phase difference of the longest interelement spacing. A ma jor advantage of this method is that even the shortest interelement spacing can be larger than half-wavelength.
