改进的指挥仪型空空机炮射击火控模型

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

对于空空机炮射击瞄准问题,传统的指挥仪模型在计算过程中假设目标的加速度不变,而在实际的空战过程中,目标的运动方式比较接近于匀速圆周运动。改进的指挥仪型火控模型,基于目标作匀速圆周运动的假设,进行火力控制算法的建模,给出了计算火控诸元的公式。通过针对不同的目标运动方式进行数字仿真,证明与传统的指挥仪型火控模型相比该模型具有更高的精度。

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.
