【摘要】 在不考虑探测器非均匀性影响的情况下,本文分析了传统四象限测角算法和另外几种算法在计算入射光的俯仰角和偏转角时的性能,还比较了在整个平面内各个算法得到的俯仰角的误差曲面。从比较中看出,采用曲线拟和的方法,硬件实现简单,测角精度也比较高。更多还原

【Abstract】 Taking no account of the non-uniformity of the detector,this paper analyzed the performance of the traditional four-quadrant angle-measurement algorithm and two other algorithms in calculating the pitch angle and the deflection angle of the incident ray,and also compared the error curve of the pitch angle calculated by each algorithm in the full plane.In comparison,it is that by using the curvefitting method,the hardware implementation is simple and the measured angle has a high precision.更多还原
