【摘要】：传统的检校安置角误差的方法依靠人工量测重叠航带同名特征间的偏移来估计安置角误差,但是同名特征的真实位置难以获取,并且人眼瞄准误差的存在降低了检校精度。因此设计了一种定标器来解决同名特征的获取难题。首先介绍了定标器的结构特点和设计原理,然后制作了缩放模型并进行了半仿真地面扫描实验,分析了定标器的可用性。最后制作了实物进行飞行实验进一步证明其设计的合理性。研究结果表明定标器的设计是合理的。
[Abstract]:The traditional method of calibrating the settlement angle error is based on the migration between the same name features of the overlapped ship belt by manual measurement, but the true location of the same name feature is difficult to obtain. And the existence of human eye aiming error reduces the accuracy of calibration. Therefore, a calibrator is designed to solve the problem of acquiring the same name features. Firstly, the structural characteristics and design principle of the calibrator are introduced. Then the scaling model is made and the semi-simulation ground scanning experiment is carried out to analyze the availability of the calibrator. Finally, a flight experiment is made to further prove the rationality of the design. The research results show that the design of the calibrator is reasonable.
