航母姿态对光电标校装置测量精度的影响分析

摘要

Considering the calibrating requirements for the carrier landing system,we deduce a model for truth-value calculation of the angle and distance by using photoelectric calibration devices according to the coordinates transformation principle.The impact of the attitude changes of the ships and the measurement error of the equipments on the calibration accuracy is analyzed,and the error computational formula of the theoretical truth-value of the distance and angle of the device is deduced based on the error propagation theory.The numerical simulation results of Matlab verify that the proposed method meets the requirements of the calibration accuracy of the system.%针对着舰引导系统标校工程的需要,根据坐标变换原理推导一种利用光电标校装置获取角度和距离的真值计算模型.分析了标校过程中舰艇姿态变化以及设备测量误差对标校精度的影响,并基于误差传递理论推导了设备距离和角度理论真值的误差计算公式.通过Matlab数值仿真结果验证本文方法能满足系统标校精度要求.
