摘要

以菲律宾海典型的水下声道为例[1-3]，利用模式理论通过数值模拟确定，在 R.A. Vadov [1-3]对爆炸信号传播进行实验研究期间，首次在声场时空结构中观察到弱发散波束的表现：在海洋波导相应点的某些位置，除了经典的四重脉冲外，还出现了与之相关的时间延迟很小的附加声信号。

Effect of a Weakly Divergent Acoustic Beam on the Spatiotemporal Structure of Pulsed Signals in an Underwater Sound Channel

On the example of an underwater sound channel typical of the Philippine Sea [1–3], it was established by numerical simulation using mode theory that during experimental studies of the propagation of explosive signals by R.A. Vadov [1–3], manifestation of a weakly divergent beam in the spatiotemporal structure of the acoustic field was observed for the first time: at certain locations of the corresponding points in the oceanic waveguide, in addition to classical quadruples of pulses, additional acoustic signals with small time delays with respect to them.
