The authors discuss high-speed implementation of the MUSIC algorithm as applied to circular array configurations. The authors first introduce the underlying signal and array models and summarize the MUSIC algorithm. The need for properly calibrating the algorithm by means of alternate array response models that incorporate mutual coupling effects between array sensors is discussed. The authors consider the circular symmetry and demonstrate how it can be utilized to devise systolic array implementation of the MUSIC algorithm complete with array calibration based on array steering vectors derived from alternate array response models
