Abstract

This application provides an obstacle detection method and vehicle based on MIMO-UWB radar. The detection method includes: transmitting pulse signals via MIMO-UWB radar and receiving reflected signals corresponding to the pulse signals via MIMO-UWB radar; performing obstacle analysis on the reflected signals to obtain obstacle information near the vehicle; wherein the obstacle information includes obstacle type, distance between the obstacle and the vehicle, and obstacle location information; and outputting the obstacle information. This application improves the accuracy of obstacle detection around the vehicle by installing MIMO-UWB radar on the vehicle and using the pulse signals emitted by the MIMO-UWB radar for obstacle detection.
