【摘要】 为了提高火控系统的装表精度,提出并实施了一种基于二维空间角发生器的测量方案。运用光学仪器理论中的矩阵方法对其进行了分析,解决了方位与俯仰方向同步测量的关键技术。为了确保采用矩阵方法对结果进行分析的精度,提出了“坐标轴系校准法”。实验结果表明,这种方案具有较高的精度,其测量不确定度小于18°,可满足测量要求,具有一定的推广应用价值。更多还原

【Abstract】 The accuracy of elevation table setting was one of the most important indexes of the photoelectric multiparameter testing system( AETS). A method based on two-dimensional space angle generator was proposed. Analyzed by matrix method in the theory of optical instrument, the key technique of in-step measurement of azimuth and pitch angle was resolved. To guarantee the accuracy of measurement, the method of system of coordinate calibration was proposed. It is proved that high degree of accuracy result was obtained in the experiment, the uncertainty of measurement is less than 18", it can meet the needs of the measurement, can be used in more field.更多还原
