| 摘要: |
| 针对浮船坞的技术特点，提出了一种基于浮船坞的动态标定方法。该方法以船艏艉线
为方位基准，以船体基准平台为水平基准，根据传统坞内标校原理，设计了标定步骤，推导
了计算公式。结果表明，雷达方位零值、俯仰零值随机误差分别约为编码器测角误差的3倍
和2倍，满足标校精度要求。该方法解决了航天测量船动态条件下的标定技术难题。 |

| Abstract: |
| In view of the technical characteristics of floating dock, a dynamic c
alibration method based on floating dock is proposed, in which the foreafter l
i
ne is taken as azimuthal datum and the hull datum platform as horizontal datum.
On the basis of traditional dock calibration principle, the calibration program
is designed and calculating formula is derived. The results show that the rand
on error in azimuthalzero is approximately three times of encoder measuring er
r
or and two times in elevationzero, which meets the precision requirment of ca
l
ibration. This method solves the difficult calibration technological problem of
TT&C ships′ measuring equipment under dynamic condition. |
