Cavitation-resistant sonar array |
摘要 |
A cavitation-resistant sonar array having reduced spacing between transducer elements is provided. The array has a series of transducer elements attached to an array fixture with spacing between elements being fixed at one-quarter wavelength or closer. Cavitation caused by this close spacing is eliminated 11 by replacing the water spaces between elements with a rho-c rubber which matches the acoustic impedance, z, of water, that is z= rho c. The rho-c material is bonded to element to prevent loss of contact between the element and the spacer. A processing computation correcting signal data is provided to account for any differences in the speed of sound, c, in the rho-c material when compared to the speed of sound in water.
