To further explain aspects of how the multi-spectral interrogator 1100 and target device 1150 operate, consider embodiments where n=3 such that the interrogator 1100 has three receive antennas and target device 1150 has three transmit antennas. In such embodiments, multi-spectral interrogator 1100 may transmit, to multi-spectral target device 1150, a first RF signal having a first center frequency (e.g., 60 GHz) using transmit antenna 1108. Multi-spectral target device may receive the first RF signal using receive antenna 1152 and generate: (1) a second RF signal having a second center frequency (e.g., 120 GHz) using frequency multiplier 1154-1, amplifier 1156-1, and filter 1158-1; (2) a third RF signal having a third center frequency (e.g., 180 GHz) different from the first and second center frequencies using frequency multiplier 1154-2, amplifier 1156-2, and filter 1158-2; and (3) a fourth RF signal having a fourth center frequency (e.g., 240 GHz) different from the first, second, and third center frequencies) using frequency multiplier 1154-n, amplifier 1156-n, and filter 1158-n. In turn, the second, third, and fourth RF signals are transmitted by transmit antennas 1160-1, 1160-2, and 1160-n, respectively.
