Abstract: An automatic direct aiming control method is proposed for self-propelled indirect aiming artillery. The proposed method can be used to make a self-propelled artillery directly aim at the fixed and moving targets without the addition of any hardware configuration of fire control system. The control model and the rapid calculation method of trajectory are studied. The aiming error and system response time are analyzed. The method can significantly improve the rapid reaction ability and firing accuracy of artillery and the automation level of weapon system.
