Acoustic Stealth Detection

Acoustic Stealth Detection - Less detectable noise footprints

Acoustic stealth and acoustic discretion play a vital role in submarine operations. Brüel & Kjær supply systems for acoustic ranging of submarines and surface ships; for noise source investigation during design and build; and for self-monitoring during operations.

Above the water and up in the skies UAVs are playing an increasing important defensive role, and have needs - just as with submarines - to be less detectable. Noise footprint and noise characterisation are important. Brüel & Kjær designs and builds arrays for noise source identification.
