- Admire its " beautiful " person, those who like is it classic form and summary area is shady dumb sound ray is temperamental. 欣赏其“美”的人，喜欢的就是它经典的样式和略带暗哑的声线气质。
- How to track sound ray of the multi-beam bathymetric in real-time and establish correction methods for different environment have become a hot pursuit in multi-beam bathymetric. 因此,针对不同的海区环境,实时对多波束测深系统的声线进行跟踪,选取或建立针对调查区的校正方法,以提高测量精度成为目前多波束勘测工作中的研究热点。
- In this paper, finite state machine is established to model the sound ray tracing which formulates the internal states and transitions of sound ray propagation. 本文采用有限状态机对声线追踪建模,给出了声线追踪内在的状态及其转移分析。
- Since environment factors influence the bend of sound ray directly, the accuracy of sound velocity profile and its correction algorithm will affect multi-beam bathymetric accuracy. 声速剖面精度及其校正方法直接影响多波束测深数据的精度,其主要原因是由于环境参数直接影响着声线折射弯曲程度。
- This means the time delay between the transmitter and the receiver is larger than the time delay between them in the condition that the sound ray is straightaway, then positioning error is caused. 海洋中声速分布是不均匀的，因此由于折射效应，声音在海洋信道传播过程中其声线是弯曲的，声线弯曲意味着声信号从发射点到接收点的传播时延大于声信号直线传播的时延，致使定位产生误差。
