Subsurface Acoustic Technology

The PAR is an end-to-end system for acoustic ranging that utilizes advanced subsurface signal processing to measure the radiated noise of submarines and surface vessels.

Cutting-Edge Technology for Measuring Radiated Noise

Passive sonar systems, which can detect submarines and ships based on their radiated noise, endanger the crews and platforms they detect. DSIT’s PAR system enables navies and shipyards to accurately measure this radiated noise, and to record and analyze the acoustic signatures of their own submarines and ships in order to monitor and control their noise and silence, thus significantly increasing their level of safety and security.

PAR’s unique design supports rapid deployment at any sea location and water depth, and saves on the maintenance involved in operating a fixed acoustic range, thus making it the most cost-effective solution for measuring the radiated noise of naval platforms over the long term.
