1. A method for providing a rear cross collision warning, comprising:
generating a grid map by dividing an area around a host vehicle into a plurality of cells arranged in lateral and longitudinal directions, and classifying the cells corresponding to positions where a stationary object around the host vehicle 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 a moving direction of the tracking target, whether the tracking target is a ghost tracking target.
