Analysis of Electro-Optical Targeting Pod Boresighting for XX Aircraft

光电瞄准吊舱(以下简称"吊舱")校靶的目的就是要求解吊舱坐标系到机体坐标系之间的三个欧拉角,并通过矩阵转换,将吊舱系下的瞄准线角度转换为机体系下的瞄准线角度,消除挂装偏差造成的影响。本文主要对吊舱的地面人工校靶和动态校靶两种方式进行分析,分析了地面人工校靶的方法及存在的不足,介绍了动态校靶的原理及方法。

The boresighting of the electro-optical targeting pod(hereinafter referred to as"pod")is to find out the solution of three Eulerian angles between the pod coordinate system and the airframe coordinate system,and convert the angle of the sighting line in the pod coordinate system into that in the airframe coordinate system by matrix transformation to eliminate the effects of installation deviation.In this paper,two boresighting modes for pod(i.e.ground manual boresighting and dynamic boresighting)are presented.The drawbacks of the manual boresighting method are analyzed,and the principle and method of the dynamic boresighting are introduced.
