Aiming at the sketchy position in the sidescan sonar image, this paper attempts to combine side scan sonar with single beam sounder and GPS in order to improve the accuracy of the target' s position. The ocean field data indicates that, compared to the conventional methods, the proposed technique has the better detection capability for the seabed target with the finer compensation.%针对海道测量中侧扫声纳位置精度低的问题,利用GPS定位数据、单波束水深数据和侧扫数据,研究侧扫声纳扫海测量中海底障碍物信息精化问题.海上试验数据表明:文中提出的多源水声测量信息联合扫测海底障碍物的方法,可改善单一侧扫系统目标探测的精度,对海底目标物扫测具有较好的适用性.
