多波束声线跟踪改进模型研究与分析
|
摘要
在分析声速变化和声波传播特性对测深值影响的基础上,阐述声线跟踪法的计算原理,对声线跟踪2个常规方法进行建模分析,并提出常声速—声线跟踪改进模型。利用实测数据,对几种声线跟踪方法进行试验分析,结果表明,常梯度声线跟踪法的计算精度最高,但计算过程繁琐,常声速—声线跟踪改进模型的计算精度较高,过程相对简单,可作为一种较为理想的声速改正后处理的方法。
Based on the analysis of the influence of sound velocity variation and acoustic wave propagation characteristics on the sounding value,the calculation principle of the sound ray tracking method is expounded,and two conventional methods of sound ray tracking are modeled and analyzed,considering the influence of sound velocity measurement error. An improved model of constant sound velocity-sound line tracking is proposed. Using the measured data,several kinds of sound line tracking methods are tested and analyzed. The results show that the constant gradient sound line tracking method has the highest calculation accuracy,but the calculation process is cumbersome.The calculation accuracy of the constant sound speed improvement method is also high,and the calculation process is relatively simple. It can be used as a method for correcting the post-sound speed correction.
