摘要
对于带有降落伞的灵巧弹来说,末敏器的目标识别算法是影响攻击精度的关键因素。利用伞-弹系统稳定下降阶段的9自由度动力学模型,分析了阵风小扰动作用下子弹姿态的运动特性;然后在末敏器的目标识别算法中融入了子弹姿态角的运动规律,用以消除子弹晃动所造成的目标识别误差。空投试验表明:融合了子弹运动学的目标识别算法有效可靠,可以提高灵巧子弹的命中精度。
For a smart munitions system with parachute, a target identification algorithm of terminal sensing device is key factor having influence on attack precision. The nine-degree of freedom dynamic model of the parachute-bomb system was developed to simulate the trajectory and the dynamic behavior of the system. By using the principle of dynamics of the parachute-bomb system, a new method was used for the target identification of a target sensitive projectile. The simulation program was developed and used. to remove the influence of wind gust. Successful airdrop tests demonstrate that the target identification algorithm combined with bomb kinematics is valid and reliable and can improve hit precision of smart munition system.
