A Method for Shape Correction of Towed Array Based on Attitude Sensor

In the field of underwater acoustic detection, tow line array is widely used, but its formation is easily distorted by water flow, vehicle movement and other factors, which seriously affects the detection performance. In this paper, an attitude sensor based flare-up correction method is proposed. The attitude sensor can obtain the characteristics of heading Angle and pitch Angle in real time. The parabola model in three-dimensional space is established. According to the actual attitude data of each element in the towed line array, the corresponding formation model is established to optimize and solve, so as to realize the accurate correction of the towed line burst. The experimental results show that this method can effectively improve the accuracy of the flareup of the towed line, significantly enhance the detection performance of the towed line array, and provide a new effective way for the correction of the flare-up of the towed line, and has broad application prospects in the fields of underwater acoustic detection and Marine safety monitoring.
