The Solstice MAS family of underwater imaging solutions combines the advantages of synthetic aperture sonar (SAS) and conventional side-scan sonar (SSS), providing ultra-high resolution, wide swath coverage and co-location of side-scan imagery and bathymetry in a low-power package.
Featuring Wavefront’s proprietary Multi-Ping Multi-Look (MPML) processing technology for enhanced signal-to-noise ratio, Solstice uses unique back-projection beam-forming technology that focuses on every single pixel in the image, and takes into account platform yaw, pitch and roll in order to reduce coverage gaps and produce distortion-free imagery.
Solstice sonar imaging systems are designed for either AUV or towfish platforms, with three variants to suit different depth and coverage requirements.
