ARRAY TECHNIQUES FOR SENSITIVITY IMPROVEMENT OF INFRA-AUDIO RECEIVING SYSTEMS,
Abstract
Results to date are reported from a study of the problem of improving sensitivity of infra-audio receiving systems by array techniques. Com parisons are made of three array types - broad side, end-fire, and circular. It is concluded that circular arrays will most nearly satisfy the requirements which are postulated for the system. Over-all signal-to-noise power improve ments in excess of 10 db are predicted. A method is proposed for achieving time delays of a few seconds, needed for phasing large arrays in air. Sampled-data and digital techniques are pd which permit selection of any possible phasing configuration by insertion of a digital word into a control unit. (Author)
