摘要

讨论了在不知道水下环境(声速分布)的情况下精确确定放置在海底的应答器位置的方法。如果将声射线的数量与应答器在海底的位置、水下参数即各层声速等未知量的数量相等，则方程的数量与未知量的数量相等。因此，不仅可以确定应答器的位置，还可以同时确定未知的水下参数。通过数值计算验证了该方法的有效性。

Precise positioning of a transponder placed on a sea floor

A method to determine precisely the position of a transponder placed at a sea floor under a condition that the underwater environment (the sound velocity distribution) is not known, is discussed. If the number of sound rays is taken equal to that of unknown quantities such as the position of the transponder at the sea bottom and the underwater parameters, namely, the sound velocities of layers, the number of equations become equal to that of unknowns. Hence, not only the position of the transponder but also the unknown underwater parameters can be determined at the same time. The effectiveness of the method is verified by numerical calculations.
