Examples relating to vehicle velocity calculation using radar technology are described. An example method performed by a computing system may involve, while a vehicle is moving on a road, receiving, from two or more radar sensors mounted at different locations on the vehicle, radar data representative of an environment of the vehicle. The method may involve, based on the data, detecting at least one scatterer in the environment. The method may involve making a determination of a likelihood that the at least one scatterer is stationary with respect to the vehicle. The method may involve, based on the determination being that the likelihood is at least equal to a predefined confidence threshold, calculating a velocity of the vehicle based on the data from the sensors. The calculated velocity may include an angular and linear velocity. Further, the method may involve controlling the vehicle based on the calculated velocity.

Calculating velocity of an autonomous vehicle using radar technology

Examples relating to vehicle motion detection using radar technology are described. An example method may involve a computing system receiving, from a radar sensor mounted on an autonomous vehicle, radar data representative of an environment of the vehicle. The method may involve the computing system, based on the radar data, detecting at least one scatterer present in the environment. The method may involve the computing system making a determination of a likelihood that the at least one scatterer is stationary with respect to the vehicle. The method may involve the computing system, based on the determination being that the likelihood is at least equal to a predefined confidence threshold, determining an indication that the vehicle is stationary. And the method may involve the computing system controlling movement of the vehicle based on the determined indication.
