ABSTRACT:
A receiver for reception of radio signals while the receiver is moving at a high speed using two or more antennas closely spaced and arranged behind each other in the direction of motion for receiving the radio signals. A signal is obtained which represents a virtual antenna that is at least temporarily stationary with respect to the environment, despite the movement of the receiver. The receiving signal of the virtual antenna is obtained under the control of a feedback signal of the receiver.
