Abstract
An angle width estimation device is configured in such a way as to include: a beam forming unit to acquire one reception array signal of a reflected wave from a target to be observed, and form, from the one reception array signal, a plurality of null beams having nulls in an arrival direction of the reflected wave, and having null widths which are widths of the nulls and different from each other; and an angle width estimating unit to compare powers of the plurality of null beams formed by the beam forming unit with each other, and estimate a null width indicating an angle width of the reflected wave on the basis of a comparison result of the powers.
