【摘要】:依据GB-SAR传感器运行导轨与成像投影面的空间关系,分别推导了导轨中心线俯仰角和横轴侧倾角所引起的成像投影误差的计算公式。计算结果表明,导轨安装定位时产生的俯仰角通常可以忽略不计,而成像投影误差对导轨横轴的侧倾角更为敏感。在GB-SAR连续变形监测应用中,导轨的横向姿态需做严格控制,确保其水平度。
[Abstract]:According to the spatial relationship between the guide rail and the imaging projection plane of the GB-SAR sensor, the calculation formulas of the imaging projection error caused by the pitch angle of the central line of the guide rail and the lateral inclination angle of the guide track are derived respectively.The calculation results show that the pitch angle produced by the guide rail is usually negligible and the imaging projection error is more sensitive to the lateral inclination angle of the guide rail axis.In the application of GB-SAR continuous deformation monitoring, the lateral attitude of the guide rail should be strictly controlled to ensure its flatness.
