摘　　要：提出一种针对水面目标的两轴上反式光电周视探测装置目标大地全方位解算方法,该方法定义一个虚拟水平或铅直入射光平面,利用光电探测装置的航向、纵摇、横摇、方位及俯仰机构转角位置量和目标一维(水平或铅直)视频偏差量,解算水平或铅直入射光平面经上反镜反射后在探测器焦平面上像线的交点,令该交点的水平或铅直坐标等于目标视频水平或铅直偏差量,可实时解算目标以装置为原点的真北方位角。经试验证明,该方法能够有效解决光电周视探测装置自主化、小型化的技术瓶颈,使光电探测装置的功能得以提升。The article supplies a method of target mother earth azimuth calculating for up-trans photoelectric detecting equipment. After defining level or plumb plane of incidence ray, using course ,roll ,pitch ,azimuth and pitching comer location value of the photoelectric detecting equipment, and target single dimension （level or plumb） video frequency dispersion to calculate the point of intersection that up-trans mirror reflect the incidence ray to the detector focal plane, making level or plumb coordinate equal to level or plumb video frequency dispersion, it can calculate north azimuth angle independently, with the target origin of the photoelectric detecting equipment. By the experimentation, the method is useful to solve technical bottle-neck for the independence and miniaturization of the photoelectric detecting equipment, also can upgrade function of the photoelectric detecting equipment.
