摘要
在严格推导常梯度声线跟踪法的基础上,提出了基于常梯度声线跟踪法的多波束声速改正精确模型,并初步推证了CARIS软件的声速改正方法。计算结果表明,精确模型计算结果与CARIS 6.1计算结果一致,并通过声线姿态改正算法比较,给出了声线姿态补偿法和直接法的适用角度范围。
After research on the MBES velocity correction model of CARIS,a new technique based on ray tracing method is promoted,and the experiment shows them have similar results.Then,the respective available areas of attitude compensate arithmetic and direct method of sounding attitude correction is been present.
