Abstract : The purpose of this research is to further the theory of signal detectability as applied to systems employing an array of antennas. The specific approach is to make use of optimal space-time liklihood ratio processing for the detection of signals which have varying degrees of uncertainty associated with them. An important aspect of this approach is that no attempt is made to use traditional beam-forming techniques. Optimal array detector design is developed by extending to array antenna systems several problems previously worked for single antenna systems. The first class of problems treated are those which involve detection of a signal of known spatial location. Included in this class are the problems of signal known exactly and signal known except for energy and/or phase. A further and more important extension of optimum array detection is the formulation of the problem of detection of signals of unknown spatial location. Here the target location is considered to be an unknown signal parameter. There is no attempt at beam-forming. (Author)
