Imagenex 837AXi "Delta T" multibeam sonar

High speed high-definition imaging empowers underwater obstacle avoidance and detection

The Imagenex Model 837AXi "Delta T" is a high-performance, low-power multibeam sonar system designed specifically for harsh underwater environments. This sonar adopts innovative digital signal processing technology and multi receiver design, with a working frequency of 165 kHz, capable of operating at depths up to 6000 meters, providing high-speed, high-resolution underwater imaging at up to 20 frames per second. Its groundbreaking 'Delta T' technology optimizes the data usage of all channels to ensure optimal resolution at every point throughout the entire field of view. This system integrates video capture, display functions, and a built-in GPS trajectory plotter, and is conveniently connected through an Ethernet interface. It is an ideal sensor for ROVs and AUVs to perform real-time obstacle avoidance, underwater search, and fine investigation.
