An antenna control device (2) controls the oriented direction of an antenna device having an azimuth axis, an elevation axis, and a cross-elevation axis, and comprises: a direction acquisition unit (20) which acquires a target direction that is a direction in which a target that an antenna (1) tracks is present; a coordinate transformation unit (7) which performs transformation into a Y-coordinate that is an angle between a plane including a Y-axis horizontally fixed within a rotation range of the azimuth axis and a zenith direction, and a target front direction, and an X-coordinate that is an angle between the target direction projected onto the plane and the zenith direction; and an arithmetic processing unit (4) which controls the oriented direction of the antenna. A driving order value computing unit (6) orders a value obtained by multiplying the Y-coordinate by a coefficient as the rotation angle of the azimuth axis. The arithmetic processing unit (4) calculates and orders an order value for the elevation axis and the cross-elevation axis such that a difference between the oriented direction of the antenna (1) and the target direction becomes an allowable value or less. |
