1. A method of imaging a target object using a device, the method comprising:
controlling the device to transmit a first radio-frequency (RF) signal having frequency content in a frequency band of 300 GHz-3 THz, the first RF signal comprising pulses having a duration between 0.1 ms and 10 ms, the frequency band having at least first and second frequency sub-bands;
receiving, using the device, a second RF signal produced by reflection of the first RF signal from the target object; and
generating a multi-channel image having a first channel and a second channel, wherein data in the first channel is determined using frequency content of the second RF signal in the first sub-band, wherein data in the second channel is determined using frequency content of the second RF signal in the second sub-band.
