MSI (Materials Systems Inc.) designs and manufactures custom sonar transducers and arrays for a wide range of applications, including side-scan, obstacle avoidance, sub- bottom profiling, swath bathymetry, mine hunting, swimmer detection, and acoustic communications. MSI's piezocomposite technology offers extremely broad bandwidth, high receive sensitivity, high source levels, and conformability for curved arrays.

Technology Profile: MSI's piezocom- posite arrays deliver broad band- width, allowing multiple beams to operate in distinct frequency bands.

This allows greater resolution and enhances broad spectrum (chirp) operating techniques. MSI's piezo- composite arrays can also be curved and shaded to achieve a specific beam pattern or to achieve a hydrodynamic profile when mounting the arrays to the curved hull of a vessel or autonomous underwater vehicle (AUV). Resonant transmit designs are in production at frequencies rang- ing 20 kHz to as high as 1MHz.

Receive arrays cover this same range and more, operating as low as 3 Hz in long-range surveillance arrays. MSI's piezocomposite arrays have been shown to meet full explosive shock requirements for Navy operations in both the USA and UK, and can be configured for full ocean depth per- formance.
