Abstract : The study program was concerned with adaptive antenna techniques which could be utilized in the 35 - 100 GHz frequency range. Included are a survey of combining methods in general; discussion of the atmospheric limitations at millimeter wavelengths including an analysis of atmospheric dispersion; a discussion of the techniques peculiar to millimeter wavelengths; and a recommended state of the art combining system using available components. Also included are recommendations for laboratory feasibility models, a millimeter wave interferometer system for atmospheric measurements and suggested development programs for components which would improve the potential and operating characteristics of the system. Throughout the study, emphasis was placed on very broad (i.e., 1 GHz or greater) bandwidth capabilities. (Author)
