Abstract
One embodiment of the invention includes a synthetic aperture radar (SAR) system. The system comprises a radar transmitter configured to transmit a combined signal, the combined signal comprising a first signal that is a modulated SAR radar signal and a second signal that is a modulated signal. The system also comprises at least one radar receiver configured to receive a reflected combined signal that comprises a reflected first signal and a reflected second signal, and to demodulate the reflected first and second signals. The reflected first and second signals can correspond to the first and second signals having been reflected from a target. The system further comprises a radar image processor configured to generate a radar image of the target based on signal parameters associated with the reflected first signal and based on information comprised within the reflected second signal.
