Method and processor for determining spatial information regarding a vehicle
11221393 · 2022-01-11 · ·

A method and processor to determine spatial information regarding a vehicle. The method includes receiving at least one initial frame of FMCW radar data including spatial information regarding the vehicle associated with a radar signal reflected back from the vehicle via a surface of at least one stationary object other than the vehicle. The method also includes receiving at least one further frame of FMCW radar data including: spatial information regarding the vehicle associated with a radar signal reflected back from the vehicle via the surface of at least one stationary object other than the vehicle, and spatial information regarding the vehicle associated with a radar signal reflected directly back from the vehicle. The method further includes using the at least one initial frame of radar data to correct for static clutter associated with the at least one stationary object in the at least one further frame of radar data.
