Marine Physical Laboratory, Scripps Institution of Oceanography, La Jolla, CA 92093-0238, USA Temporal sampling of backscattered sonar signals [Elektronische Daten] [Jules S. Jaffe] This article considers the subject of the temporal sampling of backscattered sound from an active sonar system. Here, it is demonstrated how the beam patterns of the sonar, when considered along with the velocity of the animal, prescribe a minimal sampling rate such that an unaliased version of the backscattered signal can be constructed. Thus, an equation is derived which relates a minimum sampling interval to the maximal angular velocity of targets which are moving through the beams. Observation of this minimal temporal sampling criteria is necessary in order to obtain unaliased data. © 1996 International Council for the Exploration of the Sea Regular Articles nationallicence active sonar systems nationallicence sampling theory nationallicence temporal sampling nationallicence ICES Journal of Marine Science Oxford University Press 53/2(1996-04), 359-361 1054-3139 53:2<359 1996 53 icesjms https://doi.org/10.1006/jmsc.1996.0049 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1006/jmsc.1996.0049 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Jaffe Jules S.
