Abstract
An object recognition apparatus for vehicles is provided which is equipped with a radar. The apparatus is designed to detect adhesion of any dirt to the radar which will disturbs emission of radar waves to and reception radar echoes from a target. When the number of radar waves is great which cause the times required by the radar waves to travel to and return from a target to be measured as being shorter than a predetermined period of time and the intensities of the radar returns to be greater than a predetermined value, it is determined that the dirt is adhered to the radar, thereby improving the accuracy of detecting the adhesion of dirt to the radar.
