In deep sea, sound raybending correction has to be done in order to achieve high precision of the calibration.
在深海，必须进行声线弯曲修正才可获得高精度校准结果。

Combined with the calibration method, two methods for the sound raybending correction in deep sea are developed when the sound velocity profile is known and unknown separately.
文中结合海底应答器位置校准方法，分别就声速分布已知和未知两种条件开发了深海声线弯曲修正方法。

The performance of the navigation system with a single transponder system operating in the deep sea is considered, and the corresponding methods for the correction of the sound raybending are given.
