Multi aperture side scan sonar. Developed by Wavefront Systems and manufactured and commericalized by Sonardyne, Solstice is a side scan sonar for AUVs and towed bodies. It can produce high-contrast imagery in littoral waters ranging from 600 m to less than 10 m depth, eliminating noise from multi-path reverberation, enhancing the contrast of the imagery.Multiple apertures improve the signal-to-noise ratio performance, capturing imagery at longer ranges than other sonars at the same frequency. The system also offers co-located 3D data.Each of Solstice’s 682 mm long, 2.11 kg arrays has 32 multibeam elements, allowing AUVs or towed bodies to gather more data with higher image fidelity. Solstice uses a unique back-projection beam-forming technique to focus at every single pixel in the image with 100% ground coverage.Real-time array calibration is used to dynamically re-calibrate each hydrophone element several times a second to compensate for any dynamical strains causing array non-linearity.With improved probability of detection and decreased probability of false alarms, Solstice improves the efficiency of unexploded ordnance, mine countermeasures, and search and salvage missions.Key features:
Small and compact arrays; optimized for low-logistic AUVs and towed bodies
Survey more ground in a single pass; 200 m-wide swath ensures high coverage rates
Along track resolution of 0.15°; best in class delivering maximum detection rates
Collocated side scan image and bathy improves situational awareness
Consumes only 18 W; power budget friendly increases AUV’s endurance
