| description | A method for determining location information for an airborne target includes synthesizing a cyclic transmit signal, transmitting an electromagnetic beam corresponding to the cyclic transmit signal, providing a plurality of vertically offset return signals corresponding to at least two receive antennas that are vertically offset, down-converting the plurality of vertically offset return signals with the cyclic transmit signal to provide a corresponding plurality of baseband signals, determining magnitude and phase information for each vertically offset return signal as a function of range from the corresponding baseband signal, and determining elevation information for an airborne target from the magnitude and phase information. Azimuthal information for the airborne target may be determined by tracking amplitude variations in the return signal in response to azimuthal rotation of the receive antennas. A corresponding apparatus, system, and computer readable medium are also disclosed herein. |
