The purpose of this study is to identify and quantify the difference in detections of a subsurface target from a subsurface sensor source between range-independent and range-dependent versions of the same acoustic propagation model. Environmental data were pulled from open source databases to provide an application for the comparison and using novel measures of merit, the authors were able to quantify the difference in detection performance between models. This study suggests that provided multiple types of environments are considered, it is possible to use a range-independent model to give good approximations to the accuracy of detections, one would achieve using a full range-dependent sound propagation model.

使用范围无关模型与范围相关模型量化声学目标检测的影响

本研究的目的是识别和量化同一声传播模型的距离无关版本和距离相关版本之间从地下传感器源检测地下目标的差异。从开源数据库中提取环境数据以提供用于比较的应用程序，并使用新颖的衡量标准，作者能够量化模型之间检测性能的差异。这项研究表明，如果考虑到多种类型的环境，则可以使用与范围无关的模型来很好地近似检测的准确性，可以使用全范围相关的声音传播模型来实现。
