The LOS locating system is composed of two main components  which are an inertial reference frame to provide coarse LOS locating and a 2-axis Fast Steering Mirror to remove the frame's residual error. The azimuth and elevation of LOS are both affected by the FSM two-degree-of-freedom rotation  which should be dealt with to raise the accuracy of LOS location. This paper extrapolates LOS locating algorithm of FSM by coordinate transformation  and gives corresponding deviation analysis for different LOS poiting angles. It is found that the angle deviation grows rapidly with range of FSM's travel enlarging  so the deviation must be eliminated. Through the data analysis for deviation  a non-linear compensation algorithm is proved effective to reduce the error of LOS significantly. Taking LOS changing in [-3 deg  3 deg] as an example  two analytic expressions are given  and the LOS locating accuracy rises by 34 times compared with non-linear compensation unused  and the cross coupling of LOS loating is 0.08%. 2011 IEEE.   基于同步移相技术的1/4波片快轴方位角的实时测量 期刊论文  OAI收割 Chin.
