AN/SSQ-101B Commandable Passive Sonobuoy
NATO A-size commandable passive search sonobuoy with a 40-hydrophone pentagon array, in-buoy beamforming and 8-hour operating life.
Description
The SSQ-101B is a NATO A-size sonobuoy engineered for the U.S. Navy for commandable passive search. When deployed it forms a horizontally oriented, pentagon-shaped pattern of forty hydrophones. Each hydrophone output is digitized, serialized and beam-formed within the buoy, then transmitted over a minimum 5 W FSK-modulated radio link.
Key features
- 40-hydrophone pentagon array with in-buoy beamforming
- High-precision digital compass for bearing accuracy
- EFS selects RF channel, depth, processing mode and acoustic band before launch
- UHF CFS downlink for commands after deployment
- Operating life 8 hours; operating depth 19.8-152.4 m (65-500 ft)
Applications
- Wide-area passive anti-submarine search
