ABSTRACT:
A vehicular optical radar apparatus can identify various types of obstacles as well as a preceding vehicle, thereby ensuring a reliable identification of the preceding vehicle running in the same lane as with a subject vehicle on which the apparatus is installed. A scanner scans light emitted from a light emitting device and radiates it. A light receiving device receives the light which is radiated by the scanner and is then reflected by an object. A received-light intensity detection device detects an intensity of the reflected light received by the light receiving device. An obstacle identifying device identifies the object according to the distribution pattern of the received-light intensity detected by the intensity detection device, such a pattern being obtained with respect to the direction of scanning performed by the scanner.
