In this paper, the evaluation method for DOA (Direction Of Arrival) estimation accuracy using the spectrum width is proposed, and its effectiveness is examined. It is numerically shown that the actual accuracy can be estimated by the proposed method. Moreover, computational resources can be saved because the number of trials of proposed method is decreased compared with conventional method. It is also shown that the error of the proposed method is reduced less than 0.1deg, in range of SNR = 0 to 20dB.
