基于目标爆炸运动特性的测角精度评价方法

Angle Measurement Accuracy Evaluation Method Based on Target Explosion Motion Characteristics

针对光电经纬仪野外测角精度评价不准确的问题,提出了考虑目标爆炸特性的高精度评价方法。分析了药柱爆炸时在多个方向观测获得火光图像各异的特征,研究了药柱爆炸时的运动漂移特性,通过消除药柱爆炸运动变化对评价光电经纬仪测角精度的影响,建立了一种适用于野外采用药柱爆炸评价多台光电经纬仪测角精度的模型。该模型应用在实际任务中的结果表明:改进评价方法与常规评价方法的结果趋势一致,但改进评价方法精度明显高于常规评价方法,可以应用在工程实践中。

Aiming at the problem of inaccurate evaluation of angle measurement accuracy of photoelectric theodolite in field,a high precision evaluation method considering target explosion characteristics is proposed.This paper analyzes the different characteristics of the fire image observed in multiple directions when the explosive column is exploded,and studies the motion drift characteristics of the explosive column.By eliminating the influence of the movement change of the explosive column on the evaluation of the angle measurement accuracy of the photoelectric theodolite,a model suitable for evaluating the angle measurement accuracy of multiple photoelectric theodolites in the field is established.The results of the application of the model in practical tasks show that the results of the improved evaluation method are consistent with those of the conventional evaluation method,but the accuracy of the improved evaluation method is significantly higher than that of the conventional evaluation method,which can be applied in engineering practice.
