M72-500 Submarine Noise Augmentor

LOKI Submarine Noise Augmenter

Generates a range of passive high-fidelity sonar signatures including narrow-band tonals, broadband swaths, and transients.

Sub-compact design leverages breakthroughs made with VLF transducers developed for marine seismic use. These transducers produce high power levels in the 10 hz – 1 kHz band and are significantly smaller than the previous state of the art.

SourceView sonar processor used for signal generation. Incorporates active source control allowing for continuous output of complex waveform generation – including broadband swaths – save, recall, ping generation, ping scheduling & playlist.
