要約(日本語): This paper proposes a higher-resolution angle estimation technique by introducing an antenna-element-space pseudo-peak suppression (APPS). An antenna element space canceling suppresses a pseudo peak that appears in a spatial spectrum for two angularly close incident waves. The proposed APPS will be experimentally validated using a typical single-chip radar evaluation board with a 3 Tx and 4 Rx MIMO architecture. The experimental results confirmed that the proposed APPS successfully resolved ground-placed pseudo-targets having an 0.3°angle difference of 0.3°. The proposed radar also identified on-road multiple plastic water bottles. The experiments using a vibration generator validated that the vibrations caused by driving vehicles help the APPS method provide accurate target identification performance.
