摘要

This report reviews the underlying theory of the phased array and then examines one of its most limiting problems--the blind angle. The theory of the phased array is developed by studying a simple two element array and then progressing to multi-element arrays. Following this,the progressive phase shift is incorporated into the driving currents and its result examined. The blind angle phenomenon is presented and then a physical reason for its occurrence is sought. The mutaual coupling concept is demonstrated by examining mutual impedance as a function of spacing. Then the two predominate theories,surface wave and modal,offering a physical insight into the phenomenon are examined. Considerable attention is devoted to the 'Ghost Mode Hypothesis'of Oliner,et al. and the work of Louis Stark. (Author)
