Direction-Of-Arrival Estimation Methods in Interferometric Echo Sounding
sensors Review Direction-of-Arrival Estimation Methods in Interferometric Echo Sounding Piotr Grall * , Iwona Kochanska and Jacek Marszal Faculty of Electronics, Telecommunications and Informatics, Gdansk University of Technology, Narutowicza 11/12, 80-233 Gdansk, Poland; [email protected] (I.K.); [email protected] (J.M.) * Correspondence: [email protected] Received: 24 May 2020; Accepted: 20 June 2020; Published: 23 June 2020 Abstract: 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. -

State of the Art in Swath Bathymetry Survey Systems
International Hydrographie Review, Monaco, LXV(2), July 1988 STATE OF THE ART IN SWATH BATHYMETRY SURVEY SYSTEMS by Christian de MOUSTIER (*) Paper originally presented at the symposium on ‘Current Practices and New Technology in Ocean Engineering’ held by the American Society o/ Mechanical Engineers (ASME) in New Orleans, Louisiana, 10-13 January 1988, and reprinted with the hind authorization of the symposium’s organizers. Abstract In the last decade, advances in real-time computing and data storage capabilities have led to significant improvements in bathymetric survey systems and the single point echo-sounder has now been replaced by a variety of high- resolution swath mapping sounding systems. This paper reviews the state of the art in the non-military swath bathymetry mapping systems. Such systems are typically multi narrow beam echo-sounders or interferometric side-looking sonars with swath width capabilities ranging from 0.75 to 7 times the water depth. The paper compares the design characteristics and the echo processing methods used in a number of these systems manufactured in Japan, Finland, Norway, the U.K., the U.S.A. and West Germany. 1. INTRODUCTION The outcome of a bathymetric survey is a map of water depths in a geographic reference frame. In rivers, estuaries, navigational channels, harbors and in shallow coastal waters, concerns for navigational safety underscore the need for such surveys. In tne open ocean, the incentive for bathymetric surveys is mostly of an exploratory nature, although seamounts are potentially hazardous to submarine navigation. Knowledge of seafloor relief helps marine geologists draw inferences on the dynamic processes that shape the Earth. -

In some cases, this interference affects image interpretation and downstream processing such as target recognition or bottom classification. -

Low-frequency ocean noise has increased in recent decades, often in habitats with seasonally resident populations of marine mammals, raising concerns that noise chronically influences life histories of individuals and populations. In contrast to physical harm from intense anthropogenic sources, which can have acute impacts on individuals, masking from chronic noise sources has been difficult to quantify at individ- ual or population levels, and resulting effects have been even more difficult to assess. This paper pre- sents an analytical paradigm to quantify changes in an animal’s acoustic communication space as a result of spatial, spectral, and temporal changes in background noise, providing a functional defini- tion of communication masking for free-ranging animals and a metric to quantify the potential for communication masking. -
