Abstract
A radar apparatus measures an azimuth angle with a calculation device that performs super-resolution angle measuring processing in which relative speeds and relative distances among target objects are calculated, when two azimuth angles are obtained for a given target object that has been detected, the calculation device performs an other-signal detection processing in which, among other detected target objects, a target object is searched whose azimuth angle is the same as one of the two azimuth angles and whose beat frequency upon frequency-increasing modification or frequency-decreasing modification is the same as that of the given target object; and when, through the other-signal detection processing, another target object that satisfies the condition is detected, the calculation device eliminates one of two azimuth angles of the detected given target object, which is equal to the azimuth angle of said another target object detected through the other-signal detection processing.
