Ranging and communication combining scheme for FMCW radar

Abstract

FMCW (Frequency Moderated Continuous Wave) radar in millimeter wave is an attractive technique to measure distance. It is often used for an inter-vehicle radar to avoid accidents. When data can be modulated to the FMCW radar, it will realize a more robust system because important information can be obtained from the neighbor vehicle, such as velocity, steering wheel direction, brake strength, etc. The dual mode system and OFDM radar have been proposed as the ranging and communication combined systems [1].
