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.
