TRAPS – Towed Reelable Active Passive Sonar

Compact ASW Performance

TRAPS (Towed Reelable Active Passive Sonar) is a family of variable depth, active passive sonars. With its robust and modular design and advanced, flexible sonar processing, TRAPS is an ideal choice for navies seeking high-performance anti-submarine warfare (ASW) capabilities while increasing fleet flexibility. TRAPS is available in containerized, organic, and USV variations.

Description

In conjunction with GeoSpectrum’s software processing, TRAPS provides surface ships such as OPVs, corvettes, ships of opportunity, and USVs with high-performance active and passive sonar capability for detection, classification, tracking, and localization of underwater targets. TRAPS can be part of an integrated ASW suite including multiple sonars, torpedo defense systems, underwater communication, and bathythermograph systems.

TRAPS easily adapts to different mission requirements through its revolutionary frequency customization; the active source has interchangeable LF, MF and HF blades which can be swapped on board in less than 30 minutes.
