中文摘要：

从侧扫声纳各类数据的特点出发,通过构建声纳图像的地理编码模型,提出侧扫声纳图像地理编码方法,将声纳回波数据与定位数据一一对应。实验数据结果表明：该方法是合理可行的,不仅较好地处理了定位数据,消除了拖鱼轨迹线上的折点和扇形裂缝,而且可实现海底回波点的地理定位。

英文摘要：

Based on the characteristics of various data acquired from side scan sonar, a geocode method for side scan sonar images is put forward through building the geocode model of sonar images, which achieves one-to-one correspondence between the positioning data and echo data. The experiment results prove the feasibility of this method, which can better process the positioning data, eliminate the line inflection and sector gap on the towfish trajectory, and realize geographic positioning of echo point on the seabed.
