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.

• 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。
