A method of estimating a reflected wave arrival direction using a radar apparatus includes obtaining a first, reflected signal by performing transmission and/or reception of radio waves using a first directional distribution pattern of sensitivity, obtaining a number of first targets by estimating a number of targets in a reflected wave based on the first reflected signal, obtaining a second reflected signal by performing transmission and/or reception of radio waves using a second directional distribution pattern of sensitivity, obtaining a number of second targets by estimating a number of targets in the reflected wave based on the second reflected signal, obtaining a third reflected signal by performing transmission and/or reception of radio waves using a third directional distribution pattern of sensitivity, obtaining a number of third targets by estimating a number of targets in the reflected wave based on the third reflected signal, and estimating the number of targets and the direction of presence of the targets using the numbers of the first, second and third targets and the first, second and third directional distribution patterns of sensitivity. |
