Based on the setting of the initial velocity decrease caused by the ablation of the gun by the gunpowder detonation and the velocity of the warhead in the bore, the equation of state of the initial velocity decrease during the life cycle of the barrel is derived. Using this equation of state, the automatic discriminant rule for the end of life of the barrel can be obtained under different conditions of loading and bombing; the equations of state of other error sources that cause the initial velocity deviation are jointly connected, and then the Kalman step prediction is used. In the sense of unbiased minimum variance, a recursive expression of the initial velocity deviation correction based on the speed radar is given.
