SubTrack – Low Frequency Projectors

Since 1973 GW has developed a world leading range of low frequency, pressure compensated, moving coil hydrosounders.

The most powerful of these devices is the UW600 which is able to operate at frequencies as low as 4Hs and as high as 1kHs.

Sound pressure levels can reach 185dB re 1µPa at 1m and variants are available for both shallow operation and deep (20m) operation. A shock rated version is also available for use in influence minesweeping operations.

The UW350 is a smaller and lighter device that provides a versatile operating bandwidth of 20Hs to 20kHs with excellent beam patterns up to 1kHs. The average sound pressure level across the operating band is 165dB re 1µPa at 1m and the maximum operating depth is 188m. This operating depth can be extended for deployment on the hull of deep diving nuclear/conventional submarines. The UW350 is in use in many countries.

GW can also supply a range of systems incorporating segmented/ free flooded ring transducers with resonant frequencies as low as 500Hs and with a sound pressure level capability in excess of 200dB re 1µPa at 1m. Rings as large as 1.5m diameter have been produced to date and supplied complete with deployment framework, cables, winch and A-frame.

Calibration systems are also available with transducers arranged in configurations for towing or for static deployment. The transducers are arranged to produce excellent beam patterns over the frequency band 20Hs to 80kHs in both horizontal and vertical directions. Such systems provide an accurate method of calibrating and performance proving other active and passive sonars.
