Claim 7:
8. A radar method, comprising:
establishing, with a first transceiver set, a first virtual antenna array comprising a first plurality of virtual antennas wherein all respective virtual antennas of the first plurality are substantially uniformly spaced by a distance D2;
establishing, with a second transceiver set substantially identical to the first transceiver set, a second virtual antenna array comprising a second plurality of virtual antennas wherein all respective virtual antennas of the second plurality are substantially uniformly spaced by the distance D2; and
establishing a separation distance D4<N*D1 between the first transceiver set and the second transceiver set to overlap the first virtual antenna array and the second virtual antenna array such that a portion of the first plurality of virtual antennas and a portion of the second plurality of virtual antennas alternate in spaced adjacency, such that the alternating virtual antennas are separated by a distance D2/2.
