To provide a radar apparatus capable of rapidly detecting an object at the end of a detecting range. The present invention provides a radar apparatus comprising a radar sensor that transmits a transmitting wave to a predetermined angular range and receives a reflected wave reflected by an object and a processing unit that obtains a peak of strength from a distribution of strength for angle of the received reflected wave and determines the direction of the object based on the peak. The processing unit detects the reflected wave at the end of the angular range and, when the peak is not detected, determines whether the object exists in the direction of the end of the angular range, based on the distribution of strength of the detected reflected wave.
