摘要
对分层海洋中本征声线的求取方法进行了改进。在本征声线模型基础上,分别利用二分法、单点弦截法对初始掠射角进行了精确计算和分析,结果表明,单点弦截法在保证精度的基础上节省了计算时间。计算结果可以为分层海洋本征声线建模提供理论依据。
This paper presents an modified method for searching eigenrays in stratified ocean.The Dichotomy method and Single-point chord intercept method are introduced.Based on the hydro acoustics model,exact initial angles are calculated and analyzed by the two methods.The results show that,the calculation time of the Single-point chord intercept method is least,when it ensures the precision of calculation.
