| 摘 要： | 为了揭示多波束测深系统波束宽度对水深点垂直不确定度和水平不确定度的影响,采用理论分析和实验验证的方法,证明了波束宽度对不确定度的作用随波束倾斜角度的增加而增大;给出了波束宽度导致的垂直和水平误差计算模型,提出了波束宽度效应改正模型。该成果为准确计算水深点不确定度提供了理论依据。 |

| Abstract: | For the sake of open out the effect of multibeam system beam width upon the total vertical uncertainty and total horizontal uncertainty are analyzed,after theoretic analyze and experiment validate method,The vertical error and horizontal error model caused by beam width was proved,the effect is increased along with the beam slope angle augmentation.The beam width effect correct model was proposed,and the results indicate the model can be used in high precision uncertainty calculate. |
| Keywords: | multibeam system uncertainty beam width sounding point |
