| 摘 要： | 针对捷联成像寻的器，首先给出体视线和弹体姿态到惯性视线的映射关系，然后通过推导映射函数的雅克比矩阵，给出了从体视线和弹体姿态到惯性视线的误差传递公式。通过分析误差传递增益的范数，讨论了弹体姿态和弹目相对位置对惯性视线角计算的影响。由于体视线受到成像寻的器视场的约束，其角度测量值较小，合理简化了误差传递公式，给出了惯性视线误差的近似计算公式。最后应用蒙特卡洛实验，验证了近似计算公式的精度和结论。

| Abstract: | For strapdown imaging homing seeker system,the mapping relation from body line-of-sight(LOS) angles and missile attitude angles to inertial LOS angles is described.Then its Jacobin matrix and error transfer equations are derived.The influence of missile attitude and relative position between missile and target on the inertial LOS reconstruction precision is analyzed,and then an approximate error calculation equation of inertial LOS is obtained by rational simplification.At last,Monte Carlo simulations are conducted to verify the approximation precision and conclusions. |
