OVERVIEW: Wake detectors are specialized passive or active sensor systems used to identify the underwater wake signature of submarines or torpedoes. These systems exploit disturbances or anomalies in water caused by moving underwater vehicles.

GENERAL DESCRIPTION: Wake detectors use optical, acoustic, or chemical sensing techniques to detect and track the bubble trails, turbulence, or thermal variations left behind by submarines or other submerged objects. Deployed from ships, submarines, or airborne ASW platforms, they assist in tracking otherwise stealthy targets by identifying indirect movement cues.

ROLE SUMMARY:
Category: Submarine Detection
Primary Use: Wake-based detection of underwater vehicles
Function: Passive/active tracking via water disturbance
Platform: Surface ships, submarines, airborne ASW assets
