Abstract
A radar apparatus using a pulse pair method to quickly measure a relative speed of an object. The radar apparatus includes: A data acquirer that acquires data relating to a pulse width, a repetition frequency, and a highest staggered ratio; A staggered pattern output unit that outputs a specific staggered pattern in which a total of phase changes within a sweep range of the target of the pulse pairing can be approximated to zero, wherein each phase change is caused by the pulse pairing on a target object at a constant speed due to a difference between an average transmission interval and a transmission interval between transmissions within the sweep range; And a setter that sets the transmission interval of a pulse signal by using the pulse width, the repetition frequency, the highest staggered ratio, and the specific staggered pattern.
