Attitude Integrate Monitor System Design for Direction Finding of Vector Hydrophone on Buoy Platform

In theory, a single vector hydrophone can achieve high-precision direction finding. However, when applied to a buoy detection platform, the influence of sea currents, tides and other sea conditions often causes complex changes such as tilt, sway and rotation affects Obtain the true position of the target. Based on the above problems, this paper designs and implements a set of gesture integrated monitoring system to correct the Direction Finding errors caused by the complex attitude of the buoy platform and determine the true orientation of the target. After the lake experiment proved that the system can be stable and effective real-time monitoring of underwater platform three-dimensional attitude, and effectively improve the buoy platform vector hydrophone accuracy.
