| 针对复合制导空空导弹截获目标时导引头预置天线角度与导弹允许截获不在同一时刻这一问题，建立了一种新的截获概率估算模型。根据中末制导交接班时导弹截获目标的算法流程，确立了导弹截获目标的条件，分析了影响导弹截获概率的主要误差源，建立了各误差数学模型，并通过等效转化法将弹目指示位置向量在三维空间的散布转化为弹目实际相对位置向量在三维空间的散布，完成截获概率估算模型的建立。该模型利用已知的误差先验估计及导弹飞行过程中的测量信息，可在一次弹道计算中解算导弹截获概率。利用此模型采用控制变量法分析了各误差因素与截获概率的关系，仿真结果表明：目标截获概率对数据链周期和测角精度敏感性最高。 |

| Abstract: |
| Aiming at the problem that the angle of the seekers preset antenna and the missiles permissible acquisition are not at the same time when the combined guidance air to air missile acquires the target，a new acquisition probability estimation model is established. According to the algorithm flow of missile acquiring target in hand off from midcourse to terminal guidance，the condition of missile acquiring target is established and the main error sources affecting the acquisition probability of missile are analyzed. The mathematical models of various errors are established. The dispersion of the indicating position vector of missile and target in three dimensional space is transformed into the actual relative position of missile and target by the equivalent transformation method to complete the establishment of the acquisition probability estimation model. The model can calculate the acquisition probability of a missile in one trajectory calculation by using the known error prior estimation and the measurement information during the missile flight. Using this model，the relationship between the acquisition probability and the error factors is analyzed by the control variable method. The simulation results show that the acquisition probability is the most sensitive to the data refresh rate and the accuracy of angle measurement. |
