应用全站仪综合测量火炮偏离角及俯仰半径

摘要

提出一种应用全站仪进行火炮偏离角和俯仰半径的综合测量方法。应用最小二乘原理拟合出火炮俯仰半径，然后解算出火炮偏离角，并用Monte Carlo方法分析了测量结果的精度。结果表明：全站仪高低角和火炮仰角的测量精度均对火炮偏离角和俯仰半径的测量结果无明显影响；全站仪测距精度对火炮俯仰半径测量结果的影响较大；全站仪水平角测量精度对火炮偏离角测量结果的影响明显。该方法在现场操作时需要重点关注全站仪水平观测角和测距的检测精度。%A method of comprehensive measuring for gun deviation angles and pitching radius based on total station is proposed. The least square method is applied in fitting for gun pitching radius, then gun deviation angles are calculated,and Monte Carlo method is adopted to analyze accuracy of measurement. The result shows that measurement accuracy of total station elevation angles and gun elevation angles are no significant effect on the results of gun deviation angles and pitching radius;total station range accuracy greater impact on the measurement results of gun pitching radius;total station horizontal angles accuracy significantly affect the measurement results of gun deviation angles. Application of this method for site operation,need to focus on the detection accuracy of total station horizontal angles and distances of observation.
