Abstract
In an object detecting system, a first discriminating unit discriminates an object which has a reflected wave having a reception level calculated by a reception level calculating unit, equal to or larger than a first reference level. A second discriminating unit discriminates an object, the distance to which, calculated by a distance calculated unit, is equal to the distance to the object discriminated by the first discriminating unit, and which has a reflected wave whose reception level calculated by the reception level calculating unit is equal to or smaller than a second reference level. A virtual image determining unit determines the object discriminated by the second discriminating unit as a virtual image of the actual existing object discriminated by the first discriminating unit. A virtual image deleting unit deletes the virtual image from the result of the recognition provided by an object recognizing unit, whereby only the actual existing object including no virtual image can be detected correctly. Therefore, it is possible to prevent the misdetection of an object due to a ghost beam generated by the deposition of ice or the like on a light transmitting face.
