脉冲对脉冲相干多普勒声纳系统已经商业化近20年了。这些系统在困难的环境中提供非侵入性、高精度、低噪声的数据。脉冲相干剖面仪还能够测量非常小的单元尺寸，并提供比标准多普勒系统多得多的流动细节。多波束双静态测绘系统允许在特定范围的单元上测量速度，每个波束提供来自近距离测量体积的数据，从而消除了对具有发散波束的单站系统所需的流动均匀度假设的需要。虽然已经演示了一些双静态分析原型系统，但还没有商业平台可以提供具有成本效益的交钥匙解决方案，以提供带有配套的显示和处理软件工具的三个分量数据配置文件。本文将描述一个这样的系统，Nortek Vectrino-II。在描述仪器的硬件和软件功能之后，将讨论仪器使用的一些新功能和算法。将给出拖车的数据以及与PIV系统的比较。
Pulse-to-pulse coherent Doppler sonar systems have been commercially available for almost two decades now. These systems provide non-intrusive, high accuracy, low noise data in difficult environments. Pulse coherent profilers are also capable of measuring very small cell sizes and provide far more details of flow than standard Doppler systems. Multi-beam bi-static profiling systems allow measurements of velocity over a specified range of cells with each beam providing data from closely spaced measurement volumes, thereby removing the need for assumptions of flow homogeneity as required for mono-static systems with diverging beams. While a few bi-static profiling prototype systems have been demonstrated, there have been no commercial platforms available that provide a cost-effective, turn-key solution for providing three component data profiles with accompanying display and processing software tools. This paper will describe one such system, the Nortek Vectrino-II. A description of the instrument hardware and software capabilities will be followed by a discussion of some of the novel features and algorithms used by the instrument. Tow tank data and comparisons with a PIV system will be presented.
