Abstract:

A transceiver having a virtual array is disclosed that includes a transmit antenna array and a receive antenna array. The transmit antennas are spaced apart by a transmit array spacing. Similarly, the receive antennas are spaced apart by a receive array spacing. One of the receive and transmit arrays has more antenna elements than a ratio of either the transmit array spacing divided by the receive array spacing or of the receive array spacing divided by the transmit array spacing.
