Broadband automatic water column deviation measurement method, system and device and computer medium

The invention discloses a broadband automatic water column deviation measurement method, system and device and a computer medium, and the method comprises the following steps: tracking a target, and arranging and limiting a plurality of water column detection wave gates in front and back limiting ranges of a target tracking wave gate; the method comprises the following steps of: scanning a water column by adopting a broadband signal and a simultaneous multi-beam technology to form a high-resolution two-dimensional image containing information of a plurality of water columns, and obtaining drop point positions and time of the plurality of water columns; and comparing the obtained multiple water column drop point positions with the position of the target center to obtain a deviation result between the two positions. The broadband automatic water column deviation measurement method provided by the invention reduces manual intervention errors, and has the characteristics of high detection speed, high impact water
