There is provided a calculation device for a radar apparatus which is configured to specify a direction of a target based on respective reception signals of a plurality of antennae. A calculation unit is configured to use a predetermined estimation algorithm of estimating angles of targets corresponding to a preset separable-number from the respective reception signals, set an arbitrary separable-number to generate a mode vector from the estimated angles of the targets, obtained by the predetermined estimation algorithm, and determine whether the set separable-number is proper or not based on a magnitude of an orthogonal component calculated from the mode vector and an input vector of the respective reception signals. |
