A novel self-calibration scheme for rotating array antennas is proposed.It is based on the acquisition of some near field samples using a static probe providing information about the actual behavior of the antenna.If any error, fault or obstacle modifies the desired behavior, the weights applied to the feedings of the array elements are modified so that specifications are fulfilled again.Additionally, coupling between the elements of the arrays is also accounted for.Different disciplines such as near field to far field transformation, antenna modeling, adaptive filtering or automatic learning are involved in this system.Some significant results are also presented.
