A study of the turbulent flow and character of the water masses over the Sicilian ridge in both summer and winter
(NATO. SACLANTCEN, 1972/09)The western sill region of the Strait of Sicily lies between Sicily (Capo Lilibeo) and Tunisia (Cap Bon) and is part of the submarine ridge separating the eastern from the western Mediterranean. [Fig. lJ. It was studied ... -
Bathymetry, gravity and magnetism in the Strait of Sicily
(NATO. SACLANTCEN, 1972/09)In cooperation with SACLANTCEN, O.G.S. started in 1961 the geophysical survey of the Mediterranean Sea (Allan, Morelli, 1971 ), which after 1966 was continued in the seas around Italy on the oceanographic ships of C.N.R. ... -
Design of synthetic aperture sonar systems for high-resolution seabed imaging (tutorial slides)
(NURC, 2006/10)This tutorial reviews the key aspects of the design of synthetic aperture sonar (SAS) systems for -
Magnetic, gravity and depth surveys in the Mediterranean and Red Sea
(NATO. SACLANTCEN, 1965/04)This report is a copy of a paper published in Nature, Vol. 204, 4965, 1964: 1245-1248 by T.D. Allan of this Centre, H. Charnock of this Centre at the time of the surveys but now of the National Institute of Oceanography, ... -
Micro-bathymetry data acquisition for 3D reconstruction of objects on the sea floor
(CMRE, 2019/06)This paper describes an effort to capture micro-bathymetry data for the end purpose of 3D object reconstruction, using an AUV-borne multibeam echo sounder. Due to the combination of relatively narrow across-track coverage ... -
Swath bathymetry and SAS autofocus using a Chirp source
(NATO. SACLANTCEN, 1997)Swath bathymetry and SAS autofocus can both be treated as problems in correlating echoes from a scatterer distribution on the seabed. Using a chirp source, the phase derived from quadrature match-filtering can replace the ...
