Forward looking sonar mosaicing for mine countermeasures
(CMRE, 2019/06)Forward looking sonars (FLS) are nowadays popular for many different applications. In particular, they can be used for Automatic Target Recognition (ATR) in the context of Mine Countermeasures. Currently, ATR techniques ... -
Fostering marine robotics through competitions: from SAUC-E to ERL Emergency 2018
(CMRE, 2019/05)Marine robotics competitions and challenges are today very popular in the robotics community. Their value mainly lies in the opportunities they provide to teams (both student and professional) for developing and testing ... -
Fostering the use of JANUS in operationally-relevant underwater applications
(CMRE, 2017/11)This paper presents the use of JANUS in operationally-relevant underwater applications. JANUS is an open, simple and robust digital coding technology currently in process to become a NATO standard. Two underwater scenarios ... -
Frequency deviation indicator
(NATO. SACLANTCEN, 1963/11)A new type of discriminator was developed to measure the frequency variation of electrical signals; it has the special feature to indicate without any delay the difference between the signal frequency and some fixed reference ... -
From data to decision: an overview of CMRE's information supply chain
(CMRE, 2019/06)Proper data curation is a prerequisite for the creation of long-lasting value from scientific datasets and for the generation of authoritative data-driven decision support tools. Availability of detailed information on ... -
Gamified approach in the context of situational assessment: a comparison of human factors methods
(CMRE, 2019/05)Decision support tools are increasingly common in daily tasks, with a core component of enhancing user Situational Awareness required for an informed decision. With the goal of informing the design of automated reasoners ... -
Gas bubbles in the sea: a review and model proposals
(NATO. SACLANTCEN, 1975/10)The literature pertaining to both free bubbles (pt 1) and bubbles associated with fish anotomy (pt 2) is reviewed with particular emphasis on their distributions in the sea and influencing factors. An attempt is made to ... -
Generic Oceanographic Array Technologies (GOATS)'98: bi-static seabed scattering measurements using autonomous underwater vehicles
(NATO. SACLANTCEN, 1998/10)The GOATS'98 experiment was performed May 5-29, 1998 in shallow water off Marciana Marina, on the island of Elba, Italy. The experiment addressed some of the fundamental issues associated with using the new Autonomous Ocean ... -
Geo-acoustic inversion of the PROSIM'97 experimental data using simplex simulated annealing
(NATO. SACLANTCEN, 2000/01)In the spring of 1997 SACLANTCEN performed an experiment near the Elba island in the Mediterranean Sea. The PROSIM'97 experiment was designed for the validation of a broadband acoustic propagation model. During the period ... -
Geo-spatial tactical decision aid systems: fuzzy logic for supporting decision making
(NURC, 2006/08)Tactical decision aid systems support -
Geoacoustic inversion using multipath pulse shape
(NURC, 2008/09)Experimental data, measured in a shallow water region of the Mediterranean Sea, are used to show that the variation of received intensity with time is well described by existing expressions [Harrison and Nielsen, J. Acoust. ... -
Geoacoustic modeling of the seabed at higher frequencies
(NATO. SACLANTCEN, 1997)In propagation at higher frequencies, local fluid motion in "hidden coordinate" systems and local discontinuities due to gas bubbles and bioturbation have a perturbing effect on the wave field. To model these effects, a ... -
Geoacoustic models for selected shallow water areas
(NATO. SACLANTCEN, 1996/07)This report summarizes recent work on characterization of shallow water -
Geoenvironmental characterization of selected shallow-water sites on the western European continental shelf (SWAP)
(NATO. SACLANTCEN, 1995/04)Geoenvironrnental analyses for four experiment sites on the continental -
Geometrical properties of underwater sound propagation

GLider Acoustics Sensing of Sediments (GLASS): experiments and data analysis
(CMRE, 2013/12)Seabed characteristics (geoacoustic properties and scattering strength) are critical parameters for sonar performance predictions. However, this bottom information is considered very difficult and expensive to achieve in ... -
Glider-based seabed characterization using natural-made ambient noise
(CMRE, 2019/06)Seabed characteristics (geoacoustic properties and scattering strength) are critical parameters for sonar performance predictions. However, this bottom information is considered very difficult and expensive to achieve in ... -
