| บทคัดย่อ/คำอธิบาย | : | Acoustic eigen rays (rays connecting the source and receiver) have been indentified and their turning depth, path length, travel time etc. evaluated. Acoustic intensity loss due to mean environmental conditions, vergence along acoustic rays and the low frequency absorption due to the presence of boric acid and magnesium sulphate, etc. have been estimated. For a source-receiver distance of 300 km, computed intensity loss due to spreading for different eigen rays varies between 92 and 116 dB while that due to absorption is about 4.25 dB at 0.2 kHz and 15.25 dB at 0.4 kHz source frequencies for ranges of 300 km. This analysis can be applied to for target detection and source localization problems |
