The invention discloses a shallow water underwater iron target detection method and device, the method and device can be applied to a shallow water underwater iron target detection system comprising a workboat, a floating body and a near-bottom detection towed body, and the method comprises the following steps: when the floating body drags the near-bottom detection towed body to move, the near-bottom detection towed body is driven by the floating body to move; first position information of the floating body is collected through the first positioning sensor, second position information of the near-bottom detection towed body is collected through the second positioning sensor, and earth magnetic field change information is collected through at least two magnetic field sensors; and according to the first position information, the second position information, the earth magnetic field change information and a preset height, determining whether an iron target exists underwater and at least one of the position information and the buried depth of the iron target. The method and the device are suitable for detecting the shallow underwater iron target, the construction is simple, the operation cost is low, and a more accurate detection result can be obtained.

    本申请公开了一种浅水水下铁质目标探测方法和装置,该方法和装置可应用于包括作业船、浮体和近底探测拖体的浅水水下铁质目标探测系统,该方法包括:在所述浮体拖动所述近底探测拖体移动的过程中,通过所述第一定位传感器采集所述浮体的第一位置信息,通过所述第二定位传感器采集所述近底探测拖体的第二位置信息,并通过至少两个磁场传感器采集地球磁场变化信息;根据所述第一位置信息、所述第二位置信息、所述地球磁场变化信息以及预设高度,确定水下是否存在铁质目标以及所述铁质目标的位置信息和埋藏深度中的至少一项。该方法和装置适合对浅水水下铁质目标进行探测,施工简单,作业成本低,且能取得更准确的探测结果。
