The present invention relates to a method for determining a phase correction value in a radar apparatus provided with an array antenna comprised of a plurality of antenna elements as a receiving antenna. The method for determining the phase correction value according to the present invention has a first step of obtaining a first correction value for each channel for correcting a phase shift between channels of the plural antenna elements, a second step of obtaining a second correction value for each channel for correcting a deviation between an electrical center direction and a front direction obtained with phase correction using the first correction values, and a third step of obtaining a final correction value for each channel from the first correction value and the second correction value, and the method determines such a phase correction value as to match the direction of 0 DEG with the electrical center direction for each channel.
