ABSTRACT:
An apparatus or method, for characterizing carrier waves according to the direction in which the carrier waves are transmitted or received, comprises radiating or receiving from a position which is moved repetitively along a line of motion having a predetermined, fixed location in a frame of reference. The radiating or receiving position may be moved so that at least one of the speed and direction of motion is abruptly changed. The radiating or receiving position may be moved back and forth along two non-parallel, straight lines of motion, whereby elevational and aximuthal angles of propagation are determinable solely responsively to the amplitude of the frequency shift induced by the changes in direction of the motion along the lines of motion.
