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 19):
The system of  claim 18 , wherein the system further comprises one or more computers that are programmed to perform a division in such a way that:\n (a) the division comprises dividing a numerator by a denominator to calculate a quotient; (b) the numerator is a signal from the first tag, as measured by the reader after being relayed by the relay; (c) the denominator is a signal that is measured by the reader and that is from the second tag which is housed with the relay in the vehicle; (d) the quotient is a signal that has a phase; and (e) the phase of the quotient depends on a first distance and does not depend on a second distance, the first distance being distance between the first tag and the full-duplex analog relay, and the second distance being distance between the full-duplex analog relay and the reader.
