Analysis of weight jitter influence on statistical characteristics of adaptive antenna array with linear constraints

摘要

Weight jitter influence on statistical characteristics of adaptive antenna arrays with descrete gradient algorithms is studied. This correspondence addresses antenna system for maximizing signal-to-noise ratio and adaptive array with linear constraints. Expressions of fluctuation and mean radiation patterns were obtained for these types of arrays. It is shown, that weight vector jitter leads to distortions of mean radiation pattern form, which depends on the coefficient of adaptation, output power of signals and correlation coefficient of interference.
