针对复合制导体制防空导弹中末交接班问题，提出一种导引头开机截获概率估算新方法。首先，分析了影响导引头开机截获概率的主要误差源，并根据其作用机理对误差源进行了分类，然后利用等效转换方法将各误差统一转化为导弹位置散布和偏差，在此基础上推导了导引头开机截获概率计算模型和简化模型。最后，给出各误差近似计算公式和一条典型弹道的导引头开机截获概率计算结果，将计算结果与蒙特卡罗仿真结果进行了比较。该方法适用于导引头开机截获概率工程估算、分析各种误差对导引头开机截获概率的影响等工程设计问题。

The handover problem between midcourse and terminal guidance in missile with composite guidance was investiga-ted,and a new method to get target acquisition probability ( TAP) was proposed firstly,the error resources that affect the target ac-quisition probability ( TAP) were analyzed and classified according to their influences on TAP. All errors were translated to spread and drift of missile position with equivalent method. As a result,the mathematic model and its simplified form were built up.Finally, the new method was used in the typical trajectory,the TAP was calculated with given error calculating formulas,and the results were compared with those calculated by Monte-Carlo method. This model can be used to estimate the TAP,and analyze the influence of errors on TAP etc.
