【摘要】 针对拦截战术弹道导弹这一特殊任务,首先分析了导引律设计面临的新问题和比例导引律的缺陷,在此基础上为了改善比例导引律,引入了目标机动加速度和导弹轴向加速度等信息,对比例导引律进行了修正,对导引律中各参数进行了优化。仿真结果表明修正比例导引律的过载分布合理,且形式简单,具有实用价值。更多还原

【Abstract】 In this paper, first the new issues faced with in designing the guidance law and the shortcomings existing in the proportional navigation are analyzed, and then, to improve the performance of the PN, the information of the target maneuver acceleration of the interceptor is introduced to amending the classical proportional navigation law, and the parameters of the amended guidance law are optimized. Simulation results show that the new guidance law provides significant performance improvements over the commonly used classical proportional navigation law, and the overload distribution over the trajectory is reasonable.更多还原
