The Klein System D3500TF is a digital CHIRP/CW Side Scan Sonar designed for deep water surveys to 3000 m depth. The high fidelity, high definition imaging abilities make the D3500TF system an ideal and versatile tool for various deep water survey applications.
The D3500TF employs both a user selectable CW pulse and CHIRP transmission modes. Klein’s advanced broadband CHIRP signal processing technology coupled with Klein’s proprietary display algorithms, provides extraordinary long range, and high resolution seafloor acoustic imagery.
Dual simultaneous frequency (100/400 kHz) operation is standard in the D3500TF. 100 kHz provides long range, 600 m per side, search capability while 400 kHz provides higher resolution imagery for target classification to 200 m range per side.
The system includes a multiple rate telemetry link, which automatically senses and maximizes the uplink data rate based on the coaxial tow cable characteristics. Up to 5000 m of coaxial tow cable can be used with the DT3500TF or an unlimited length of fiber optic tow cable can be employed. The D3500TF towfish is designed so that the operator has plug and play interchangeability between coaxial or fiber optic tow cables without modification.
The D3500TF operates from 110/230, 50/60 kHz power sources. The standard system configuration is supplied complete with a rugged stainless steel towfish (with heading, pitch, roll & depth sensors installed), a 19” rackmount transceiver processor unit (TPU), a workstation with Windows 7 and SonarPro® software installed, and a 100 m lightweight Kevlar test/tow cable. Available options include; laptop, a safety cable, to prevent loss of the towfish should it become hung up on bottom debris, a depressor wing, a responder interface, a magnetometer interface a motion reference unit, an altimeter, and fiber optic tow cable interfaces.
