A radar apparatus includes a change amount calculation section for obtaining, for each of a plurality of peaks of a first spectrum belonging to the same group, a peak value at the present point in time and calculating the difference between the peak value and a peak value obtained before the present point in time; a ratio calculation section for comparing the obtained difference with a predetermined difference threshold and calculating a ratio of the number of peaks whose differences are greater than the difference threshold to the number of all the peaks belonging to the same group; and a pedestrian determination section for determining that the object is a pedestrian when the calculated ratio is greater than a predetermined ratio threshold and at least one of peaks belonging to the same group differs from the remaining peaks in terms of the sign of the difference. |
