摘　　要：由于空空导弹与其挂装的载机坐标不同,并且导弹在不同挂点挂载方式也不同,为了使不同挂点不同悬挂姿态的导弹武器系统平显交联一致,必须进行坐标的转换。本文对某导弹坐标转换的原理进行分析,采用硬件解调和软件校正的方法,实现了离轴角信号的精确转换,解决了平显交联中的坐标转换问题,并且成功应用。Because of the coordinates of the air-to-air missile are different from the airplane that ap- pended, and the appended modes of missile in different places are also different in the air-to-air weapon system. Coordinate conversion must be solved for the weapon systems having a same show communion with the missiles of different appended modes in different places. This paper analyses the reason of missile co- ordinate conversion, and realizes the precise conversion of abaxial angle by the way of hardware demodu- lation and software emendation, which solves the problem of coordinate conversion in the show communion and applies successfully.
