针对红外制导导弹拦截大机动目标时制导精度下降的问题,引入视线角加速度导引律,在对其原理进行分析的基础上,利用伴随系统理论对引入视线角加速度导引律后的导弹平稳性和脱靶量进行了仿真分析与验证.仿真结果表明,视线角加速度导引律能有效降低目标机动及入射角偏差所引起的脱靶量,性能良好.“,”Aiming at the decline of guidance accuracy when the infrared guided missile intercepts highly maneuverable target,the angular acceleration guidance of the line of sight is introduced.Based on the principle of the angular acceleration guidance of the line of sight,the stability and miss distance of missile are simulated and validated by using the adjoint system theory.Simulation result shows that,the angular acceleration guidance of the line of sight can effectively reduce the miss distance caused by target maneuvering or aim angle deviation.
