Acoustic swimbladder resonance spectroscopy: fundamentals in scattering theory
Francis, David T. I.; Foote, Kenneth G. (Others, 2003) -
Akustiske målinger på sild i nordlige fjorder og kalibrering av akustiske instrumenter med F/F Michael Sars, 6 - 18 desember 1989

Analysis of empirical observations on the scattering of sound by encaged aggregations of fish
Foote, Kenneth G. (Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1978) -
Angular distribution of overwintering Norwegian spring spawning herring
Huse, Ingvar; Foote, Kenneth G.; Ona, Egil; Røttingen, Ingolf (ICES CM documents, Working paper, 1994)When plankton production drops off in the fall, adult Norwegian spring spawning herring migrate to two fiords in northern Norway with stable water masses with low temperature and predation. In the wintering areas, the ... -
Angular measures of dorsal aspect target strength functions of fish
Foote, Kenneth G. (Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1980)Three angular measures of dorsal aspect target strength functions in the pitch plane are computed for previously gathered acoustic data on three gadoid fishes, two clupeoid fishes, and mackerel. These measures are the ... -
Assigning values of target strength and equivalent beam angle in acoustic surveys of fish
Foote, Kenneth G. (ICES CM Documents;1991/B:34, Working paper, 1991)Contrary to popular opinion, the equivalent beam angle (~) is not determined solely by the transducer directivity. Rather, like the target strength TS, it also depends on the scattering properties of the target fish, but ... -
Averaging of fish target strength functions
Foote, Kenneth G. (Journal article; Peer reviewed, 1980)A general model for averaging the acoustic target strength functions of fish is stated in calculable form. It accounts for the influences of the distribution of generally coupled spatial and orientation states of fish, ... -
Backscattering and extinction cross sections of two swimbladdered fishes at the lowest resonance, as modeled by the boundary-element method
Foote, Kenneth G.; Francis, David T. I. (Others, 2003) -
Bad-weather calibration of split-beam echo sounder systems
Foote, Kenneth G. (ICES CM Documents;1990/B:22, Working paper, 1990)A condition for standard-target calibration is stability of the sonar platform and target rig. This condition cannot always be met, nor need it be when the transducer has a split-beam function. Since the position of ... -
Bat sonar and the role of frequency diversity
Foote, Kenneth G.; Simmons, James A. (Others, 2006) -
Bathymetric conformal variography of the spawning stock of Northern blue whiting
Foote, Kenneth G.; Ostrowski, Marek (ICES CM Documents;1996/S:46, Working paper, 1996)Bathymetric-based conformal isotropic and anisotropic variograms are defined. These are applied to the spawning stock of northern blue whiting (Micromesistius poutassou) along the slope of the continental shelf west of the ... -
Bioacoustics and D. V. Holliday: a scientific tribute
Foote, Kenneth G. (Others, 2004) -
Broadband echo spectra from euphausiids and copepods
Foote, Kenneth G.; Knutsen, Tor; Atkins, Philip R.; Bongiovanni, Claire; Francis, David T. I.; Eriksen, Peter K.; Larsen, Mette Torp; Mortensen, Tom (Others, 2000) -
Calibrating parametric sonars for backscattering applications
Foote, Kenneth G. (Others, 2006) -
Calibration reflector
Foote, Kenneth G. (ICES CM Documents;1989/B:4, Working paper, 1989)Calibration of scientific echo sounders and integrators entails, inter alia, measurement of the dynamic range. This can be done by repeating on-axis measurements of echoes from each of two different standard targets. ... -
Calibration sphere for low-frequency parametric sonars
Foote, Kenneth G.; Francis, David T. I.; Atkins, Philip R. (Journal article; Peer reviewed, 2007)The problem of calibrating parametric sonar systems at low difference frequencies used in backscattering applications is addressed. A particular parametric sonar is considered: the Simrad TOPAS PS18 Parametric Sub-bottom ... -
Calibration trials with multibeam sonars
Chu, Dezhang; Foote, Kenneth G.; Baldwin, Kenneth C.; Mayer, Larry A.; McLeod, Andrew; Hufnagle, Lawrence C. jr.; Jech, J. Michael; Michaels, William (Others, 2003) -
Coincidence echo statistics
Foote, Kenneth G. (Journal article; Peer reviewed, 1996)Two scatterers at similar range give an echo which may appear to be due to a single scatterer. Methods for determining target strength that depend on resolving single scatterers may fail in this instance. Statistics ... -
Coincidence echo statistics
Foote, Kenneth G. (ICES CM Documents;1994/B:40, Working paper, 1994)Two scatterers at similar range give an echo which may appear to be due to a single scatterer. Methods for determining target strength that depend on resolving single scatterers may fail in this instance. Statistics associated ...
