Abstract:
A full-duplex analog relay may comprise an analog uplink relay and an analog downlink relay, and may relay signals between a transmitter and a backscatter node. The spectrum of the downlink signal transmitted by the downlink relay may be different than the spectrum of the uplink signal received by the uplink relay. Filtering may attenuate leakage from the downlink relay to the uplink relay, and vice versa. The uplink relay may create a phase offset that is opposite in sign and substantially equal in magnitude to the phase offset created by the downlink relay. The downlink and uplink relays, taken together, may created a substantially constant net phase offset. The full-duplex relay may be housed in a vehicle that moves, and may be used to determine spatial coordinates of backscatter sources that are located in the relay's environment.

Claim (Index 15):
A system comprising:\n (a) a vehicle; (b) a full-duplex analog relay; (c) a first transceiver; and (d) one or more computers; wherein\n (i) the full-duplex analog relay comprises\n (A) an analog uplink relay; and \n (B) an analog downlink relay, \n \n (ii) the downlink relay is configured to receive wireless downlink signals from the first transceiver and to transmit the downlink signals to a second transceiver, \n (iii) the uplink relay is configured to receive wireless uplink signals from the second transceiver and to transmit the uplink signals to the first transceiver, \n (iv) the downlink relay is configured to create a first phase offset in the downlink signals, \n (v) the uplink relay is configured to create a second phase offset in the uplink signals, the second phase offset being opposite in sign and substantially equal in magnitude to the first phase offset, \n (vi) the full-duplex analog relay is housed in the vehicle, \n (vii) the vehicle is configured to move in a trajectory, and \n (viii) the full-duplex analog relay is configured to, at different times while the vehicle moves in the trajectory, relay the uplink signals in such a way that spatial coordinates of the second transceiver are inferable from information about the trajectory and from phase of the uplink signals as received by the relay.
