AquaVision X400 Subsea Forward-looking Sonar

AquaVision X400 Subsea Forward‑looking Sonar

400 kHz · 40 Hz · 6,000 / 11,000 m

  • 40 Hz acoustic video — Up to 512 beams per ping, refreshed at 40 Hz for smear-free imaging of moving scenes and fast avoidance response.
  • 250 m forward warning — 400 kHz with 1° horizontal resolution outlines large targets at distance, leaving the vehicle room to manoeuvre.
  • Full-ocean-depth solid-state design — All-digital solid-state array in rugged pressure housings; 6,000 m and 11,000 m versions.
  • Clear picture in turbid water — Built-in adaptive noise reduction holds image quality in high suspended sediment and complex bottom returns.
  • Secure supply and support — Independently developed core components and algorithms — short lead times, stable supply and long-term technical support.

AquaVision X400 is a subsea multibeam forward-looking sonar for obstacle avoidance and forward situational awareness on deep-sea vehicles. Operating at 400 kHz, it sees through turbid, zero-visibility water where optical cameras fail, and gives up to 250 m of warning ahead of the vehicle.

A fully digital beamforming (DBF) architecture refreshes a 120° forward sector at up to 40 Hz, producing a real-time acoustic video of the scene ahead. Two pressure ratings are offered — 6,000 m and 11,000 m (full ocean depth) — without trading structural strength for weight, making AquaVision a dependable safety layer for work-class ROVs and long-endurance AUVs in complex deep water.
