Due to the power limit of warhead section and singleness of attacked targets, the early man-portable missiles are usually designed with contact fuze and provided with remarkable effect to attack large targets like helicopters. In recent years, as small targets like cruise missiles and UAVs come forth, the combat efficiency of the man-portable missiles with contact fuze is greatly decreased. In order to increase the combat efficiency to attack the small targets, most man-portable missiles are designed with proximity fuze. For the characteristics of high precision and small warhead of man-portable missiles, a calculation method and model for time-delay of fuze-warhead coordination is put forward and optimized in design, which will increase the fuze-warhead coordination efficiency for man-portable missiles to attack the small targets and bring high practical value to the design of fuze-warhead coordination of man-portable missiles.%早期的便携式导弹受战斗部威力限制和射击目标单一,通常采用碰炸引信,在射击直升机类大目标效果显著.近年来,随着巡航导弹和无人机等小目标的出现,使得采用碰炸引信的便携式导弹作战效能大大降低.为了提高对付小目标的作战效能,多数便携式导弹上均采用了近炸引信.本文根据便携式导弹的精度高和战斗部小的特点,提出了便携式导弹引战配合延迟时间计算方法和计算模型,并进行优化设计,从而提高便携式导弹对付小目标的引战配合效率,对便携式导弹的引战配合设计有一定的实用价值.
