Abstract: A radar apparatus transmits a radar wave, with a control parameter being set to a desired value, and acquires an initial transmission level from outside the radar apparatus, the initial transmission level being a result of measurement of a transmission level of the radar wave. At the same time, the radar apparatus receives a delayed wave of the radar wave from outside the radar apparatus, and acquires an initial reception level which is a result of measurement of a reception level of the delayed wave. The radar apparatus then sets a target reception level according to a preset target transmission level, and the initial transmission level and the initial reception level acquired. The radar apparatus then repeats update of the control parameter and measurement of the reception level until the reception level coincides with the target reception level.
