摘要相干多普勒声纳为在野外和实验室条件下探测边界层流动提供了强有力的工具。然而，这种技术的速度剖面应用是复杂的特征速度和距离模糊。任何应用程序的正确实现都需要仔细的设计，以便可以准确地预测性能。本文提出了一种能够模拟相干多普勒工作的计算机模型。点散射体模型在三维中操作，并适应双基地换能器的几何形状。模型模拟和实验室试验之间表现出良好的一致性。一些简单的模型应用。该模型已开发的剖析应用程序，但同样适合于建模点测量声学多普勒测速仪。
Abstract Coherent Doppler sonar provides a powerful tool for probing boundary layer flows under field and laboratory conditions. However, velocity profiling applications of this technique are complicated by characteristic velocity and range ambiguities. Proper implementation for any application requires careful design so that performance can be accurately predicted. In this paper, a computer model capable of simulating coherent Doppler operation is presented. The point scatterer model operates in three dimensions and accommodates bistatic transducer geometries. Excellent agreement is demonstrated between model simulations and laboratory trials. Some simple model applications are presented. The model has been developed for profiling applications but is equally suited to modeling point measurement acoustic Doppler velocimeters.
