| ■要約(日本語) |
This paper proposes a method to improve the angle estimation accuracy for multiple targets having significantly different radar cross sections (RCSs) in automotive millimeter-wave radar based on frequency-modulated continuous wave (FMCW) and fast chirp modulation (FCM) techniques. The proposed radar introduces an antenna element space interference can-cellation (AIC) method enabling the discrimination of the different RCS targets. For establishing reliable target detection on the road, the automotive radars need to identify the various sizes of targets, including trucks, cars, bikes, bicycles, pedestrians, animals, and other obstacles. The large targets affect the small targets through the sidelobes in the radiation pattern of an antenna array, degrading small target detection and its angle estimation. The AIC method enables reducing the coupling effects between the targets. Experiments on angle measurements for three different RCS targets validated the effectiveness of the AIC method. A radar evaluation board used in the experiments consists of a single-chip millimeter wave FMCW radar integrated circuit (IC) and printed 3 Tx and 4 Rx MIMO radar antennas. |
