Abstract

A computer-implemented method for detection of ground surface height variation in a vicinity of a vehicle is disclosed. The method comprises acquiring (by processing circuitry of a computer system) measured backscatter from a radar transceiver mounted on the vehicle and directed at the ground surface, comparing (by the processing circuitry) the measured backscatter to expected ground surface backscatter according to a current vehicle motion, and detecting (by the processing circuitry) a ground surface height variation responsive to a difference between the expected ground surface backscatter and the measured backscatter satisfying a detection criterion. In some examples, the difference may indicate one or more of: a distance from the radar transceiver to the ground surface height variation, and an angular orientation relative the radar transceiver of the ground surface height variation. Corresponding computer system, vehicle, computer program product, and non-transitory computer-readable storage medium are also disclosed.
