光电经纬仪动态测角精度随机误差检测方法研究

为了实现光电经纬仪动态测角精度随机误差的检测，进一步提高光电经纬仪的检测能力，进行了光电经纬仪动态测角精度随机误差的研究。基于布尔萨坐标转换原理，通过严格理论推导，得到动靶标方位值和俯仰值的理论公式。以光电经纬仪的方位角A、俯仰角E以及采样时间t等基本参数为基础，结合动靶标方位值和俯仰值的理论公式，得到A和E的理论真值，再与光电经纬仪测得值A和E进行比较，得到光电经纬仪动态测角精度随机误差。提出一种检测光电经纬仪的动态测角精度随机误差的新方法，为光电经纬仪动态测角精度随机误差的测量提供了新的思路。

Detection method of random error for dynamic measurement accuracy of photoelectric theodolite

To achieve measuring stochastic error for the dynamic measurement accuracy of the photoelectric theodolite and to improve detection ability of the photoelectric theodolite, a detection method of stochastic error was developed. Based on Burse-Wolf model, the theoretical equation for the angle of azimuth and elevation was developed. According to the theoretical equation and based on the azimuth angle, the elevation angle and the sampling time of the photoelectric theodolite, the theoretical truth-values of the azimuth angle and the elevation angle  were obtained, and the random error was obtained from comparing the theoretical value and the measured value. A novel method for measuring stochastic error for the dynamic measurement accuracy of the photoelectric theodolite was presented.
