Terrain Obstacle Avoidance Sonar For Autonomous Vehicles

TOAS is a terrain and obstacle avoidance sonar developed to interface high information rate acoustic signals to the artificial intelligence systems being developed for autonomous underwater vehicles.This lightweight, low power sonar uses fifteen preformed beams to acquire forward looking obstacle and terrain returns which are processed by the vehicle to provide steering information. Imbedded processors control the many setable parameters of the system to tailor acoustic functions to varying vehicle environments. Options are available which adapt TOAS to the needs of specialized piloted vehicles and ROV's.
