Three dimensional precise localization method on water near-field source

通过分析目标源深度变化时聚焦波束形成二维声图法定位的特点,提出2种目标声源的深度动态扫描方法,即过阵过程深度探测法和正横时能量最大深度探测法。在理想情况下,目标声源深度的测量不仅可以实现目标声源的二维精确定位,还可实现目标声源的三维精确定位。利用理论仿真分析2种深度探测法的准确性与适用范围,并给出三维精确定位的结果。

Two depth scanning methods was developed for the goal source by analyzing underwater image mechanism in depth measurement. The two methods are process through array depth detection method and abeam energy maximum depth detection method each. Analyzing measurement result of the goal depth under ideal conditions can achieve two-dimensional accurate positioning of the goal and can also achieve three-dimensional accurate positioning of the goal. Through theoretical data analysis, it can give accuracy and applicable scope of the two methods for depth scanning and give results of three-dimensional accurate positioning of the goal.
