中文摘要:
      为了解决常规方法计算导弹俯仰角和偏航角的精度偏大的问题,提出了利用2 台光电经纬仪直接交会计 算的高精度方法。首先借助于像坐标和地面坐标的关系建立计算方程,接着将2 台经纬仪的测量元素分别代入计算 方程,建立俯仰角及偏航角的计算模型和精度估计模型,从建立的模型看文中方法没有引进导弹头、尾部坐标计算 误差。该方法应用在××任务中的结果表明:2 种方法的结果趋势一致,但文中方法精度明显高于常规方法,可以 应用在工程实践中。
英文摘要:
      In order to solve the low precision of conventional method to calculate the missile pitch angle and drift angle, the high precision method of using 2 photo-electric theodolites direct intersection calculation is presented. Firstly the calculation equation is obtained based on relationship between the ground coordinate system and the image coordinate system. Then computational model and precision estimation of pitch angle and drift angle is achieved by putting 2 photo-electric theodolites measuring elements into calculation equation. According to the model, the missile head and tail coordinate error is not used in calculating error in this paper. Apply the method to the ×× task, the results show that the results tendency of the two methods are consistent, but the precision of this paper is obviously higher than that of the conventional method, and this method can be applied in engineering practice.
