Nowadays, the underwater acoustic positioning system is the mainstream of underwater navigation and localization.

从目前来看，水声定位系统是水下导航定位的主要手段。

For underwater acoustic positioning system based on measurement of time_delay, range ambiguity appears when pulse's propagating time is longer than its repetition period.

基于时延测量的水声跟踪定位系统，当信号传播时延大于脉冲重复周期时，就会出现距离模糊。
