基于超短基线的侧扫声呐水下目标定位技术

Underwater target positioning technology of side scan sonar based on ultra short baseline

侧扫声呐测量技术是探测、搜寻水下目标的最有效的手段之一,在许多海洋工程、海事保障项目中都用到侧扫声呐测量技术。然而,因其拖曳式的测量工艺特点,无法对所探测到的水下目标进行精确的测量定位。实际作业时,往往需要通过采用多方向探测并辅以其它手段来确定水下目标的准确位置,降低了水下目标的探测效率。文中提出采用侧扫声呐与超短基线相结合的方式进行水下目标的探测方法,不但能够有效提高水下目标的测量定位精度,而且可以大大提高侧扫作业效率、降低作业成本,实用性强。

Side scan sonar measuring technique is one of the most effective means to detect and search the underwater target,it is used in many marine engineering and marine security projects.However,due to the characteristics of the towedmeasurement process,it is not able to accurately measure the underwater target.The actual operation,it is often need to use themulti direction detection and other means to determine the accurate position of the underwater target,reduce the detectionefficiency of the underwater target.We proposed the method of combining the side scan sonar with the ultra short baseline,which can effectively improve the accuracy of measurement and positioning of the underwater target,and can greatly improvethe efficiency of side scan operation,reduce the operating cost,and has strong practicability.
