Abstract

An object detecting device has components which emit electromagnetic waves by scanning a scan range in horizontal and vertical directions, receive reflected waves, obtain signal level of the received reflected waves, calculate a correction value based on vertical position of the zone in the scan range where the level of the received waves is the highest and the center position of the scan range in the vertical direction, and correct the center position in the vertical direction of the scan range based on the calculated correction value.
