SeaBeam 3012深水多波束测深系统标定方法

Research on Calibration Method of SeaBeam 3012 Multibeam Bathymetry System

以"向阳红10"科考船船载SeaBeam 3012多波束测深系统为例,对深水多波束系统的标定方法进行研究,依照海试标定试验对海上标定的步骤进行了较全面的阐述,通过标定测量得到水下换能器阵安装偏差结果,并对该系统进行了性能测试和精度评估。通过对采集到的水深数据进行分析,可知该测深系统的水深数据质量可靠,地形图能客观、合理地呈现海试区域的水深和地形地貌信息。

In this paper,the calibration method of multibeam bathymetry instrument is studied by using the SeaBeam 3012 multibeam bathymetry system with"Xiangyanghong 10"scientific research vessel,the steps of sea calibration are described in detail according to the sea calibration test,the measurement results of the underwater transducer array are obtained by calibrating the measurement,and the performance test and accuracy evaluation of the system are carried out.Through the analysis of the collected depth data,it can be seen that the depth data of the bathymetry system is reliable,the topographic map can objectively and reasonably show the depth and topography information of the sea test area.
