基于弹道修正引信的滚转角误差补偿方法

A Roll Angle Error Compensation Method Based on Trajectory Correction Fuze

为了提高弹体姿态角的探测精度,将误差分类并进行针对性校正,基于多项式拟合与反馈系统提出一种弱化随机噪声影响的误差补偿算法。该算法无需外部设备协助,可实现自我预测与校正。采用三轴转台实验机对误差补偿算法的性能进行验证,误差分析显示新方法在椭球拟合校正方法的基础上将滚转角测量精度提高到1°.转台实验结果表明,所提出的自主校正方法提高了滚转角的实时测量精度,可以很好地控制随机噪声。

In order to improve the detection accuracy of attitude angle of projectile body,an error compensation algorithm based on polynomial fitting and feedback system is proposed to reduce the influence of random noise.The algorithm can predict and correct itself without external equipment.The performance of the algorithm was verified by the three-axis turntable experiment.The error analysis shows that the algorithm is used to improve the mean measurement accuracy of roll angle to 1°on the basis of the ellipsoid fitting correction method.The experimental results of turntable show that the proposed self-correction method can improve the real-time measurement accuracy of roll angle,and the algorithm can control the random noise well.
