Apparatus, system and method for radar antenna calibration

For example, a radar device may include an input to receive radar receive (Rx) data, the radar Rx data based on radar signals received via a plurality of Rx antennas of a multiple-input multiple-output (MIMO) radar antenna; and a radar processor configured to generate radar information based on the...

Zusammenfassung:	For example, a radar device may include an input to receive radar receive (Rx) data, the radar Rx data based on radar signals received via a plurality of Rx antennas of a multiple-input multiple-output (MIMO) radar antenna; and a radar processor configured to generate radar information based on the radar Rx data by calibrating an antenna mismatch (MM) of the MIMO radar antenna, such that the radar information includes an angle of arrival (AoA) spectrum having a peak sidelobe level (PSLL) of at least 30 decibels (dB). 例如，雷达设备可包括：输入端，该输入端用于接收雷达接收(Rx)数据，该雷达Rx数据基于经由多输入多输出(MIMO)雷达天线的多个Rx天线接收到的雷达信号；以及雷达处理器，该雷达处理器被配置成用于通过校准MIMO雷达天线的天线失配(MM)来基于雷达Rx数据生成雷达信息，使得雷达信息包括具有至少30分贝(dB)的峰值旁瓣水平(PSLL)的到达角(AoA)频谱。
