<p>PURPOSE:To reduce calculation errors caused by target object speed or disturbance such as wind pressure by calculating a target object position while adding an error angle to a directional angle of an antenna by means of a computer. CONSTITUTION:A computer 3a calculates a target object position according to respective output of a movable mount 2 and an antenna 1. For example, when the mount 2 is a biaxial gimbal of an azimuth and an elevation, a specific equation relationship is established between a directional angle of the antenna 1, a target object angle and an error angle to a target object. Thereby, the computer 3a carries out calculation by a specific formula according to the error angle from the antenna 1 and the directional angle of the antenna from the mount 2, and calculates the target object angle to the standard direction of the mount 2. When the standard direction of the mount 2 is deviated from a desired measurement standard, a deviated angle is added, and a positional angle of the target object is outputted. Thereby, calculation errors caused by target object speed or disturbance can be reduced.</p> |
