摘要
根据黄海中部一次浅海声学实验获得的脉冲波形和传播损失数据进行海底声速和衰减系数的反演。本文在反演过程中:(1)考虑了海水深度的测量误差对反演结果的影响,并提出了一种消除该影响的方法。(2)反演得到的该海区海底衰减与频率呈非线性关系。(3)本文讨论了非均匀海底模型对海底反演结果的影响。
The bottom sound speed and attenuation were inverted by using the pulsed waveform and transmission loss.In the process of the inversion, (1) the effect of the depth of waer on the inversion results were discussed and a methodfor determining the depth of water was given out, (2) the inverted attenuation has nonlinear frequency relationship, (3)the effect of inhomogeneous bottom on the inverted results was discussed.
