摘　　要：新一代激光制导炸弹普遍采用陀螺稳定式导引头替代原风标式导引头以提高制导精度,为提高导引头捕获概率,针对两种类型导引头工作机理差异,对方案过载飞行段驾驶仪误差带来的弹道偏差及飞行攻角对捕获概率的影响进行了分析。引入导引头地面捕获域的概念,提出一种以名义捕获域中心与目标位置的相对距离差作为射表投弹距离修正的方法,减小了由于干扰导致弹道偏移对导引头捕获的影响。仿真计算表明,使用修正后的射表,可极大地提高导引头捕获概率。Instead of the original wind-head laser seeker, the gyro-stabilized seeker is used in new generation laser guidance bomb widely. In order to improve the acquisition probability of seeker, based on the analysis of different working mechanism between the two kinds of seeker, the influence on target acquisition probability was studied, which caused by the trajectory deviation and attack of angle from autopilot working error in the phase of zero-command planning flight. The theory of seeker acquisition ground zone was given. The relative distance error between the nominal center of acquisition ground zone and the target position was calculated and used as the bombing range modifying method of firing table, in order to decrease the influence of trajectory deviation caused by disturbance on acquisition probability. The simulation shows that the acquisition probability can be improved with the new firing table.
