| 摘 要： | 侧扫声纳在海洋工程等各方面都有广泛的应用,实际工作中经常采用拖曳方式作业,由于海洋环境的特殊性,风流对拖体的水中姿态有明显的影响,声纳测量和显示的是从拖曳载体到反射物体的距离,反射物体的实际位置依据拖体的水平姿态特性,所以其定位精度受海流等各方面影响较大。根据海洋调查侧扫声纳定位的基本原理和声纳工作的主要参考技术指标,分析对海流声纳探测目标定位精度影响,提出削弱海流影响的主要方法。 |
| 关 键 词： | 海洋测绘 侧扫声纳 误差分析 |

| Abstract: | The Side-Scan Sonar has a widespread application in the oceanographic engineering.It is used by the way of towing frequently in the practical work,as a result of the marine enviroment particularity,the posture of tow-fish in the water is affected obviously.The sonar surveys and outputs the distance from towing carrier to the reflection object.Because the physical location of reflection object is on the basis of horizontal posture of the tow-fish,its positioning accuracy will be affected by the ocean current.According to the basic rule of the Side-Scan Sonar and the main technical indicators of Sonar,the influence of ocean current on location accuracy of sonar is analyzed,and the weakening method is proposed. |
| Keywords: | hydrographic surveying and mapping Side-Scan Sonar error analysis |
