Sub Bottom Profiler

Sub Bottom Profiler

Sub bottom profiler for shallow and deep waters from Falmouth Scientific Inc., a global marine solution provider for sub bottom profiler, tide system and other marine application.

Single Channel CHIRP Sub-bottom Profiler

HMS-621 CHIRPceiver Litt

Sub-bottom profiling applications in diverse sediments in shallow water environments require compact tools as well as multiple frequency bands to support diverse survey requirements. The HMS-621 CHIRPceiver Litt and transducer arrays fill this wide range of survey needs. The user selectable frequency bands supported by the HMS-621 include standard LF (1KHz-10KHz), and HF (8KHz-23KHz). It can be easily configured for up to 50Khz with a standard single channel user configurable transceiver. CW frequencies can also be programmed within the respective band. The transducer and hydrophone arrays are configured to perform both the transmit and the receive functions of the system.

The HMS-621 CHIRPceiver Litt uses a flexible Graphical User Interface connected via Ethernet that allows the user to set CHIRP or CW modes of operation, Start and Stop frequencies, and Pulse Lengths and Power Level for the output pulses. The receiver controls allow for Gain and Attenuation as well as Diagnostic modes. All sonar data is logged in SEGY format using industry standard acquisition software such as Chesapeake SonarWiz.

Dual/Single Frequency CHIRP Sub-Bottom Profiler

The HMS-622 CHIRPceiver and its Family of Transducer Arrays and Vehicles can fill this wide range of survey needs. The frequency bands supported by the HMS-622 include standard LF (1KHz10KHz), and optional ULF (200Hz-2KHz) and HF (8KHz23KHz). It can be easily configured for up to 50 KHz with a standard 2 channel transceiver. CW frequencies can also be programmed within the respective band. The transducer and hydrophone arrays are configured to perform both the transmit and the receive functions of the system.

Hull Mounted Seismic Profiler

Extreme deep water sub-bottom profiling applications (4Km to 12Km) require an array of 16 to 36 low frequency transducers installed in a hull-mounted sea chest. An acoustic window is used to reduce the attenuation of the signal through the vessel hull for improved signal to noise of the system. The HMS-12KM system with the HMS-622 CHIRPceiver and hull mounted transducer arrays fills this range of survey requirements. The frequency bands supported by the HMS-12KM include LF (1KHz-10KHz) and HF (8KHz-23KHz) with a standard 2 channel transceiver. CW frequencies can also be programmed within the respective band. The transducer arrays are configured to perform both the transmit and the receive functions of the system.

 

 

Ultra-rugged, High-Power, Ultra Low-Frequency, Compact Sub-Bottom Profiling System

The ULF Compact Sub-Bottom Profiler is ideal for applications that require high resolution CHIRP sub-bottom images along with deeper penetration in difficult sediments such as hard-packed sand. The System generates CHIRP signals in the 200 Hz to 2 kHz frequency range and is suitable for operation in a variety of array configurations to support many different shallow water sub-bottom profiling applications. Components of the ULF System include a standard single or dual frequency CHIRPceiver, a dedicated ULF Matching Driver, the HMS-AT650 transducer, and a specialized hydrophone streamer. The HMS-AT650 transducer is based on a high efficiency piston loaded flextensional design. Single transducers can support up to 3,000W power levels at a 30% duty cycle depending on the depth of operation. Multiple transducers can be arranged in multi-element arrays to support a wide variety of beam patterns and source levels to suit most survey applications. The transducer can be either mounted on a rigid support or towed behind a small vessel

Pipeliner systems

The BPA-62X Side-Mount Arrays and Tow Vehicles are specifically designed for detecting and tracking buried pipe. The BPA-622 Dual Array is configured with two transducer arrays (low and high frequencies) and an integrated hydrophone array. The combined transmit and receive beam pattern of the BPA-622 is 80deg in the forward and aft direction and 32deg athwart for the low frequency array, and 120deg beam in the forward and aft directions and a narrow, 9deg beam athwart for the high frequency array. The BPA-621HF Arrayis configured with a high frequency transducer array with an option for a separate hydrophone array. The transmit and receive beam pattern for the high frequency array is 120deg beam in the forward and aft directions and a narrow, 9deg beam athwart.
