A method with rear cross collision warning includes: dividing a surrounding area of a host vehicle into a plurality of cells arranged in lateral and longitudinal directions; creating a grid map on which cells, among the plurality of cells, corresponding to positions where a stationary object around the host vehicle is viewed are classified as occupied cells; determining a position of a reflective structure reflecting radar signals based on a positional relationship between the occupied cells on the grid map; and determining, based on the determined position of the reflective structure and either one of a position of a tracking target viewed by the radar and moving direction of the tracking target, whether the tracking target is a ghost tracking target.
