Abstract
A method and apparatus is provided for calibrating and detecting faults in a receiver having a multi-element antenna. The method includes the steps of selecting an antenna element of the multi-element antenna and transmitting a signal through the selected element. The method further includes the steps of detecting the transmitted signal through at least one antenna element of a remaining set of elements of the multi-element antenna and calculating a phase shift for the at least one antenna element of the remaining set of elements.
