一种矢量水听器浮标补偿角挑选方

A Method of Selecting Compensation Angle of Vector Hydrophone Buoy

摘要:

矢量水听器浮标在海上试验时一般需用到真方位、声学方位、罗经值 3 个参数，但罗经安装过程中很难正对大地坐标系正北方向，海上试验前一般都需要校准。针对这个问题，采用了直方图的方法挑选矢量水听器浮标补偿角，挑选出的补偿角用于海上试验时声学测向角度补偿，保证声学方位测量的准确性。

Abstract:

The vector hydrophone buoy usually needs three parameters of true azimuth，acoustic azimuth and compass value in the sea test. As it is difficult to face due north of the geodetic coordinate system during the installation of compass，calibration is generally required before sea test. To solve this problem，the method of histogram is used to select the compensation angle of vector hydrophone buoy. The compensation angle selected is used to compensate the angle of acoustic direction during sea test to ensure the accuracy of acoustic azimuth measurement.
