Abstract
A direction detection apparatus transmits radar waves, with resultant reflected waves being received as incident waves by elements of an array antenna. Normally the direction of a target object is calculated based on analyzing respective received signals from the antenna elements, in calculations utilizing an estimated total number of incident wave directions. In an antenna direction adjustment mode, an actual number of target objects, and hence actual number of incident wave directions, is utilized in place of the estimated value, thereby enabling direction detection information to be obtained which does not fluctuate with time, thus facilitating the adjustment.
