A device for aiming at a mobile target and to direct an anti-aircraft gun is comprising servomotors for directing the barrel, an aiming unit with field glasses (8) and a device for ranging as well as a calculating unit. The aiming unit is pivotally held on a support (2, 5) fixated to the barrel. Means (11) are provided for directly and indirectly measuring the sight line angular velocity. The calculating unit calculates the required lead angle and offset angle of the barrel and is sending corresponding signals to the servomotors. The device is functioning in three phases: during a phase I the barrel angular velocities have a fixed relationship with the sight line angular pivoting achieved by manual action from a neutral position, a series of range measures are taken and the calculating unit is calculating a preliminary target path and target speed, during phase II the range measuring is stopped and the barrel is directed corresponding to the preliminary target path and target speed, during phase III another series of range measures is taken and the calculating unit is calculating definitively the target speed and thereby the correct lead angle and offset angle of the barrel direction, whereby the servomotors are directing the barrel. |
