大陆斜坡海域宽带声源的匹配场定位

Broadband matched-field source localization in the continental slope environment

摘要: 2001年在东中国海大陆斜坡海域进行了中美联合浅海声学实验。基于该次海域数据对垂直阵接收的宽带爆炸声信号进行了匹配场定位研究。结果表明,若用水平海底模型计算拷贝场,声源的定位误差较大;考虑海底倾斜后,匹配定位结果就得到很大改善,在1.0~50.0km距离范围内,大多数信号的定位结果与GPS标称距离一致。

Abstract: Broadband matched-field is applied for source localization to the vertical line array signals received in the 2001's jointed ASIAEX experiment. The experimental data results that the accuracy of the source localization is largely improved with the consideration of the slope of the bottom. The range estimates of the most bombs signals in the range from 1.0km to 50.0 km are consistent to the GPS measured.
