Abstract
A quad array acoustic imaging system used in underwater applications is discussed. In this configuration, a 2N-element crossed array results in an effective data aperture equivalent to that of a N2filled array. The underwater images of corner reflectors, wooden rods, and a planar letter E at an ultrasonic frequency of 152 kHz have shown the feasibility of the system with an electronic scanning capability.
