837A-000-403-S Delta T
OBSTACLE AVOIDANCE FIXED TRANSDUCER MULTIBEAM SONAR
The Imagenex Model 837A “Delta T” is a multiple receiver sonar system designed to provide high-speed imaging with all the advantages of underwater sonar. Innovative digital signal processing is used to optimize data usage from all channels to achieve the best possible resolution at every point in the field of view. Recent advances in computing power have made it possible to transfer and process this data at resolutions equal to computer monitor resolution, and with image frame rates of better than 20 frames per second!
The Delta T system has been designed from the ground up with the most advanced, high accuracy, low power electronic components available to provide breakthroughs in system power consumption, package size, and price. This advanced electronics package has built in flexibility and programmability to accommodate a wide range of transducer arrays. Thus, the Delta T is the first in a family of new technology products which will have imaging and profiling capabilities to suit your underwater application. Imagenex sonars: advancing underwater imaging capability for the everyday user.
Underwater Hardware Specifications
Transducer Beam Width
Receive: 120° x 10°
Transmit: 120° x 10°
Effective Horiz. Beam Width
3°, 1.5°, 0.75°
120, 240, 480
*Data is acquired at full resolution every shot: processing the data for screen display on a PC can slow the system at highest number of beams. 120 beam mode is recommended for real time data acquisition. The data can then be played back at highest resolution (480 beam).
Screen: 0.2% of range
Output: 0.02% of range
Min. Detectable Range
Max. Operating Depth
Up to 20 fps
Interface to PC
Standard: 10 Mbps Ethernet (10 BASE-T) using TCP/IP
Bit rate may vary if an Ethernet extender is in use.
