【摘要】 系统误差的存在使得对光电跟踪系统进行引导时会存在引导误差,修正系统误差有利于提高引导精度。最小二乘系统误差修正方法精度较低;球谐函数的系统误差修正方法有较高的修正精度,但不适用于三轴光电跟踪系统;BP神经网络的系统误差修正方法的修正精度比球谐函数法提高约20%,有望用到球谐函数法不适用的三轴光电跟踪系统的系统误差修正中。更多还原

【Abstract】 System errors bring on leading error. Correction of the system errors of photoelectric tracking system could improve the leading precision. Least squares system errors modifying method has lower precision than globe function system errors modifying method,and globe function method could be used in three-axis photoelectric tracking system; BP neural network system errors modifying method improves the precision than globe function method about 20% and may be used in three-axis photoelectric tracking system.更多还原
