要約(英語): Traffic accidents involving pedestrians, including children and other vulnerable people, on pedestrian crossings and intersections in residential areas are serious problems in Japan. If pedestrians can directly send specific signals to surrounding vehicles without using public wireless communication systems, drivers in the surrounding cars identify the pedestrians on roads to avoid serious traffic accidents. Automotive millimeter-wave radars have recently become less expensive because they consist of an integrated circuit (IC) and arrayed antennas on a printed circuit board. This configuration mitigates its form factor and enables radars to be lightweight. Therefore, pedestrians can wear a millimeter wave radar as a radar tag to send a dedicated signal to surrounding vehicles to avoid serious traffic accidents by notifying their presence. This paper proposes a chirp period modulation-based automotive millimeter-wave radar-to-radar communication method for zero traffic accidents involving pedestrians. The proposed chirp period modulation method is easy to apply to existing automotive millimeter-wave radars. A fast chirp modulation (FCS) based frequency modulated continuous wave (FMCW) radar worn by a pedestrian sends a chirp sequence with a long chirp period, causing impulse signals at the receiver of radars on vehicles transmitting chirp sequence with a short chirp period. Counting the number of impulse singles (impulse signal counting method) enables radars on vehicles to identify the presence of pedestrians and warn the drivers on surrounding vehicles of the presence of pedestrians. Experimental results using a millimeter wave radar validate the proposed method.
