Title (EN) A SONAR ANTENNA
(FR) ANTENNE SONAR
Abstract: front page image
(EN)This invention concerns a sonar antenna. The sonar antenna comprises an axially symmetric acoustic surface having the cross-sectional form of a generally U-shaped curve of non constant curvature. The curve is shaped to allow continuous coherent ensonification such that the power in the echo returned from a uniform flat sea floor is substantially constant. This equipment is used for underwater echo sounding and uses hydro acoustic transducers to ensonify the water and receive echoes.
(FR)L'invention concerne une antenne sonar qui comprend une surface acoustique axialement symétrique possédant une forme de section transversale qui se présente généralement en courbe en U de courbure non constante. La forme de la courbe permet une insonification continue de sorte que la puissance dans l'écho renvoyé depuis un fond marin plat uniforme soit sensiblement constante. Cet équipement est utilisé pour l'échosondage sous-marin et fait intervenir des transducteurs hydroacoustiques pour l'insonification de l'eau et la réception d'échos.
