Improved fire control model of director type air-to-air gunnery

For the aiming problem of air-to-air gunnery,the traditional director model makes the assumption that the target acceleration is constant in calculating process,but in practical process of air combat,the moving mode of target approachs to uniform circular motion.The director type fire control model is improved by modeling the fire control algorithm based on the assumption that the target does uniform circular motion.The calculation formulas of the fire control data are offered in this paper.The digital simulation of different mode of target motion proves that the model has higher precision than that of traditional director type fire control model.
