为了完成某段落弹道的保精度测量,同时保证其中的关键特征点精度最高,提出了靶场光电经纬仪最优布站方法。该方法是在设备误差和飞行弹道基本确定的情况下,将光测系统平衡程度和弹道特征点测量精度作为约束条件的优化设计,从仰角约束和交会角约束计算两方面建立特征点测量的优化设计模型;定义系统平衡概念,引入系统平衡系数计算公式,建立系统平衡程度计算模型。将方法应用于工程实践得到了满足要求的所选的布站方案,经验证,所选方案与理论布站方案相差甚小,是一个优越的布站方案,既保证了关键点测量精度又充分发挥了光测系统的最大潜能。

In order to complete the maintaining accuracy measurement task for a certain trajectory and ensure the highest accuracy of the key feature points,the optimal of the disposition of the photoelectric theodolites in this range is proposed.The method was an optimizing method subjected both to the equilibrium of the optical measuring system and the measurement precision of characteristic points when the error of the equipment and the trajectory were basically determined.Subjected to both the angle of elevation and the angle of intersection,an optimizing model for the measurement of the characteristic points was b u ilt,the equilibrium of the system was defined,the formula to calculate the coefficients of the equilibrium was introduced and the equilibrium calculating model was constructed.The proposed method is then applied to engineering practice,the results show that it is an excellent disposing method,which guarantees the measurement precision of the critical points and fully develops the potential of the optical measurement system.
