海洋地震勘探中USBL定位数据分析及处理

Analysis and processing of USBL positioning data in marine seismic exploration

本文主要讲述在海洋地震勘探中USBL定位数据的分析及处理方法,通过大量的USBL定位数据建模分析,针对分析结论研究处理方法,并将算法细分为各个步骤,逐步演示处理过程,最终将USBL定位数据提取、优选、约束、平差后计算后得到节点位置坐标。使用LBL定位结果与USBL定位结果进行对比验证,通过真实有效的数据来验证其处理流程、算法的实用性、计算结果的可靠性,得出影响USBL定位结果精度的几个重要因素。

This paper focuses on USBL positioning in marine seismic exploration data analysis and processing method,through a lot of USBL positioning data modeling analysis,study analysis processing method,and the algorithm is subdivided into various steps,step-by-step process,will eventually USBL positioning data extraction and optimization,constraints,get node coordinates calculated after adjustment.LBL positioning results are compared with USBL positioning results for verification,and real and valid data are used to verify the processing process,the practicability of the algorithm and the reliability of the calculation results,and several important factors affecting the accuracy of USBL positioning results are obtained.
