Detection of autonomous vehicle movement using radar technology

摘要

An example of vehicle motion detection using radar technology is described. The exemplary method can be performed by a computing system and may include receiving radar data representing the environment of the vehicle from at least one radar sensor mounted on the autonomous vehicle. The method may include detecting at least one scatterer present in the environment based on radar data to determine the possibility that at least one scatterer is stationary with respect to the vehicle. The method may include calculating the speed of the vehicle based on radar data in response to a possibility of at least equal to a predefined confidence threshold, the speed calculation indicating that the vehicle is stationary. It includes one of determining and determining the angular velocity and linear velocity of the vehicle. Also, the method may include controlling the vehicle based on the calculated speed.
