Abstract—The results of experimental studies on the propagation of low-frequency pulsed signals in deep- and shallow-water areas of the World Ocean are presented. Sufficient conditions have been obtained for separation rays based on their arrival time at the reception point: displacement of the ray under the influence of the downward sound velocity gradient directed exceeds displacement of the ray in the opposite direction under the influence of the gradient due to gravity; the emitter and receiver are at different depths; the emission is pulsed for a pulse duration smaller than the difference in the ray arrival times at the reception point. The experiments validated the hypothesis that the aggregate conditions are sufficient to detect rays by their arrival time.

大距离低频率下到达时间的分离射线条件

摘要—给出了低频脉冲信号在世界海洋深水和浅水区传播的实验研究结果。根据分离射线到达接收点的时间，已经获得了足够的条件：在向下的声速梯度的作用下，射线的位移超过了重力在梯度作用下在相反方向上的射线位移。 ; 发射器和接收器处于不同的深度；发射脉冲的脉冲持续时间小于射线在接收点的到达时间之差。实验证实了这样的假设：聚集条件足以通过射线的到达时间检测射线。
