| 中文摘要: |
| 本文研究了利用单个水听器的匹配场定位问题,分析了波形相关和包络相关两种处理方法。通过对均匀层条件下匹配和失配的数值模拟,讨论了运用单个水听器进行匹配定位的可行性和对浅海远距离匹配定位的可能性,以及反演海底参数的问题。从数值模拟的结果来看,运用波形相关方法进行匹配定位所得的模糊函数主瓣突出,分辩率高,是一种比较好的匹配场处理方法。最后,对一组浅海爆炸声传播实验的数据进行了匹配定位,取得了较为满意的结果。 |
| 英文摘要: |
| In this paper, we are trying to localize source with single hydrophone in shallow water waveguide by waveform correlation and envelope correlation. Firstly, numerical simulations are computed in isospeed channel, and then, a set of data obtained in shallow water experiment with explosive sound source is matched. The results manifest that the processing method matched by waveform correlation is feasible. |
