Acoustic predictions of the recently developed traceo ray model, which accounts for bottom shear properties, are benchmarked against tank experimental data from the EPEE-1 and EPEE-2 (Elastic Parabolic Equation Experiment) experiments. Both experiments are representative of signal propagation in a Pekeris-like shallow-water waveguide over a non-flat isotropic elastic bottom, where significant interaction of the signal with the bottom can be expected. The benchmarks show, in particular, that the ray model can be as accurate as a parabolic approximation model benchmarked in similar conditions. The results of benchmarking are important, on one side, as a preliminary experimental validation of the model and, on the other side, demonstrates the reliability of the ray approach for seismo-acoustic applications.
新开发的迹射线模型考虑了底部剪切特性，其声学预测与 EPEE-1 和 EPEE-2（弹性抛物线方程实验）实验的水箱实验数据进行了基准测试。这两个实验都代表了在非平坦各向同性弹性底部的类似 Pekeris 的浅海波导中信号传播，在此可以预期信号与底部的显著相互作用。基准测试特别表明，射线模型可以与在类似条件下进行基准测试的抛物线近似模型一样准确。基准测试的结果一方面作为模型的初步实验验证很重要，另一方面也证明了射线方法在地震声学应用中的可靠性。
