Abstract : The research dealt with decision theoretic antenna processing systems and the development and application of a new coherence theory to optimum antenna system design. The objective was the development of techniques that would result in improved target parameter estimates and better detection and resolution capability than those achieved by conventional systems. A new theory was developed, called transcoherence theory. It can be used to determine the optimum amplitude and/or phase shading for an antenna that is intended as an information-gathering device. It is particularly useful when employed for the purpose of compensating for deleterious medium effects. The theory can also be used to find the coherence properties of sources, where these properties are essential to the specification of the a priori statistics of target signals and clutter. A relatively simple decision theoretic processor was built and found to improve angular resolution by at least a factor of four over that of conventional systems. The research studies and their results are documented in seven scientific reports and several papers. (Author)
