Study and simulating of adaptive array processing with effect of channel uniformity

Adaptive anti-jam processing used by Global Positioning System (GPS) usually works in an environment where interferences exist. The Power-Inversion (PI) algorithm is often applied to suppress interferences in the system. But variance of amplitude and phase which exists among antenna channel takes bad effect on adaptive anti-jam processing and PI algorithm, so we do our best to research the relation between channel uniformity and adaptive processing. When variance of amplitude and phase is limited under the definite condition, paper proves PI algorithm can not only reject interferences, but also conquer channel uniformity on a certain degree by academic researching and simulating. The conclusion has the advantage to engineering applications.
