FMCW radar with broadband communication capability [PDF]
2007 European Radar Conference, 2007 The use of amplitude modulation to encode information onto an FMCW radar signal is proposed in this paper. This new technique, that has been named AM-FMCW communicating radar, provides a new channel for broadband communication by reusing the radar frequencies and without introducing any distortion in the radar functionality.
