Abstract:
In certain embodiments, a system for transmitting (electromagnetic or acoustic) wave-based signals towards a target includes a plurality of transceivers and a controller. Each transceiver transmits a probe signal towards the target and receives an associated backscatter signal corresponding to reflection of the probe signals from the target. The controller determines, for each transceiver, a Doppler frequency shift and a time delay, modifies each associated backscatter signal based on the corresponding Doppler frequency shift and time delay to generate an associated motion-compensated backscatter signal, and applies time reversal (TR) processing to each motion-compensated backscatter signal to generate an associated motion-compensated TR signal. Each transceiver transmits towards the target a transmission signal based the associated motion-compensated TR signal. In communications systems, the transmission signals are data-modulated versions of the motion-compensated TR signals. In radar and sonar systems, the transmission signals are the motion-compensated TR signals.

Claim (Index 1):
A method for transmitting wave-based signals towards a target, the method comprising:\n (a) transmitting a probe signal from each of a plurality of transceivers towards the target; (b) receiving, at each transceiver, an associated backscatter signal corresponding to reflection of the probe signals from the target; (c) determining, for each transceiver, a corresponding Doppler frequency shift for the associated backscatter signal; (d) determining, for each transceiver, a corresponding time delay for the associated backscatter signal; (e) modifying each associated backscatter signal based on the corresponding Doppler frequency shift and the corresponding time delay to generate an associated motion-compensated backscatter signal; (f) applying time reversal (TR) processing to each associated motion-compensated backscatter signal to generate an associated TR signal; and (g) transmitting, from each transceiver, an associated transmission signal based the associated TR signal towards the target.
