一个由多个广泛分布的传感器组成的多静态主动声呐系统必须在传感器之间共享信息。如果声学通信是用于共享信息的手段，它可以消耗系统总能源预算的很大一部分。本文建立了浅水水声通信网络的能量消耗模型。该模型考虑了水柱中声速剖面和海底成分等环境因素。该模型采用波导不变性的概念，有效地结合了通信信号的宽带特性。数值结果表明，与直接通信相比，在中间传感器之间中继消息可以节省大量的能量。计算还表明，能源消耗的变化可能超过一个数量级，这取决于海床的组成。
A multistatic active sonar system with several widely distributed sensors must share information between the sensors. If acoustic communication is the means used to share information, it can consume a significant fraction of the system's total energy budget. In this communication, an energy consumption model is developed for a shallow-water acoustic communications network. The model includes the environmental factors like the sound-speed profile in the water column and the composition of the seabed. The model uses the waveguide invariant concept to incorporate efficiently the broadband nature of the communications signals. Numerical results demonstrate how relaying messages between intermediate sensors can save substantial energy compared to direct communications. The calculations also show that energy consumption can vary by more than an order of magnitude depending on the seabed composition.
