It should be appreciated that although in the illustrative embodiment of FIG. 11A, the target device includes three or more transmit antennas (and, consequently, three or more signal transformation chains), in some embodiments, a multi-spectral target device may include only two transmit antennas and two signal transformation chains (e.g., all the components of target device 1150 whose labels end with “-1” and “-2,” but not those components whose labels end with “-n.” Additionally, although there are “n” separate transmit antennas shown as being part of target device 1150, that number of transmit antennas may be reduced by combining at least some of the transmit antennas (e.g., two transmit antennas) into a single transmit antenna using a multiplexer (e.g., duplexer). This may reduce the size of the target device.
