PROBLEM TO BE SOLVED: To provide an method for calculating orientation position having satisfactory precision, without increasing a scale of an orientation radar system. SOLUTION: A plurality of capturing position information for a target such as a shell is acquired by the orientation radar system, An air drag coefficient and a drift coefficient for the target are calculated based on the capturing position information, and an orientation position of the target is calculated while applying the air drag coefficient and the drift coefficient in a trajectory equation, when calculating a trajectory by a sector method.
