Signature Management

Acoustic and Anechoic Signature Control

Trelleborg has a wide range of products to improve the signature of underwater platforms by reducing radiated noise and target strength. Our core products are tiles (anechoic and decoupling tiles, transmission loss and decoupling materials), sonar materials (replaces glass reinforced plastic for sonar domes and windows), RhoC materials (designed to match the impedance and speed of sound in seawater), damping materials and encapsulation systems (large and small scale encapsulation of arrays with controlled exotherm).
