地面动态跟踪精度试验中的坐标系变换研究

Research on the coordinate transformation in dynamic tracking accuracy test

为了简便有效地对光电产品进行检测,在地面模拟飞机实际飞行环境下进行地面运动目标跟踪精度试验,提出了将目标的GPS位置信息转换为产品坐标系下的坐标的变换方法,经过Matlab仿真计算,这种变换方法得到的目标基于产品的方位、俯仰角符合实际情况,适合计算跟踪精度。

In order to detect the photoelectric products capability of tracking moving target simply and effectively in the ground instead of on the plane, the coordinate transformation method of how to convert the data from the target GPS position information to coordinates based on the products is designed in this paper. After Matlab simulation, using this coordinate transformation method, the calculated azimuth and pitch angle based on the products coordinates is inline with the actual situation.The azimuth and pitch angle can be used to calculate the tracking accuracy.
