Nowadays, there are two leading sea sounding technologies: the multibeam echo sounder and the multiphase echo sounder (also known as phase-difference side scan sonar or bathymetric side scan sonar). Both solutions have their advantages and disadvantages, and they can be perceived as complementary to each other. The article reviews the development of interferometric echo sounding array configurations and the various methods applied to determine the direction-of-arrival. "Interferometric echo sounder" is a broad term, applied to various devices that primarily utilize phase difference measurements to estimate the direction-of-arrival. The article focuses on modifications to the interferometric sonar array that have led to the state-of-the-art multiphase echo sounder. The main algorithms for classical and modern interferometric echo sounder direction-of-arrival estimation are also outlined. The accuracy of direction-of-arrival estimation methods is dependent on the configuration of the array and external and internal noise sources. The main sources of errors, which influence the accuracy of the phase difference measurements, are also briefly characterized. The article ends with a review of the current research into improvements in the accuracy of interferometric echo sounding and the application of the principle of interferometric in other devices.
如今，有两种主要的海洋测深技术：多波束回声测深仪和多相回声测深仪（也称为相差侧扫声纳或测深侧扫声纳）。这两种解决方案都有其优缺点，并且可以被视为相互补充。本文回顾了干涉式回声测深阵列配置的发展以及用于确定到达方向的各种方法。“干涉式回声测深仪”是一个广义术语，适用于主要利用相位差测量来估计到达方向的各种设备。本文重点介绍了导致最先进的多相回声测深仪的干涉式声纳阵列的改进。还概述了经典和现代干涉式回声测深仪到达方向估计的主要算法。到达方向估计方法的准确性取决于阵列的配置以及外部和内部噪声源。还简要描述了影响相位差测量准确性的主要误差源。本文最后回顾了当前关于提高干涉式回声测深准确性的研究以及干涉原理在其他设备中的应用。
