Abstract

In this paper we present the basic method for determining the range and bearing of objects by performing spatial interferometry upon the mm-wave phasefront it radiates. A three-port quasi-optical circuit is used as an example of how this technique may be employed. The paper considers the simplest possible case of locating a single coherent source in order to establish the basic principles of the method.
