Abstract
A device includes a receive antenna configured to receive a radar signal. The device includes a return signal generator configured to generate a return signal based on the received radar signal. The return signal includes at least a first component at a first frequency offset from a carrier frequency of the received radar signal and a second component at a second frequency offset from the carrier frequency. The device also includes a transmit antenna configured to transmit the return signal.
