Abstract: A microwave imaging system is provided. The microwave imaging system comprises a dual-comb transceiver module and a processing module. The dual comb transceiver module comprises a transmitter module for transmitting an output signal, at least one receiver module for receiving the output signal from the transmitter via a channel and for generating a first output signal, and a reference receiver module for receiving a portion of the output signal transmitted by the transmitter module via an attenuator module and for generating a second output signal. Further, one or more channel parameters associated with the microwave imaging are determined based on the first output signal and the second output signal.
