During the past week in the waters of Puget Sound near Seattle, Marport engineers completed successful sea trials of its Multimode Sonar Transceiver.

The broadband, Multimode Sonar Transceiver is based on Marport’s Software Defined Sonar technology.

A single transceiver is capable of providing the following functional capabilities via dynamic software reconfiguration:

-  single beam shallow water survey sounder,

-  single beam deep water survey sounder,

-  multibeam echo sounder,

-  side scan sonar,

-  doppler current profiler,

-  doppler velocity log,

-  sound velocity profiler, and

-  sub bottom profiler (conventional and parametric).

Other features of the transceiver include:

  • Dynamic Broadband Tuning  -  1 kHz to 1 Mhz
  • Shallow Water to Full Ocean Depth – 0.35 to 10,000m
  • User Defined Frequency, Pulse Length, Modulation
  • Advanced Algorithms for Bottom Tracking, Second Layer Detection and Seabed Classification
  • Support for 3rd Party Transducers and Software
  • User Defined Frequency, Pulse Length, Modulation
  • Transceiver is MIL-SPEC Type Approved
  • Simultaneous Support for 4 Different Transducers/Operating Frequencies
  • Embedded Intel Celeron Dual Core Processor
  • Integrated Linux RTOS
  • Solid State Hard Drive for Data Logging
  • Interfaces include CANBus, Giga-Ethernet, USB, RS232/422, Bluetooth, WiFi
  • Compact, Lightweight, and Power Efficient
  • Excellent Price / Performance Value

The completely watertight, cylindrical transceiver has a diameter of 20 cm and is rated  to 5,000m depth (for AUV operations).

Preliminary technical specs are as follows:

Transmitter

  • Modulation fully programmable – CW, FM, Phase
  • Pulse length fully programmable
  • Broadband Frequency: 1 kHz to 1 MHz
  • Output power: up to 4kW on 20 Ohms
  • Full IQ 16 bit pilot signal

Receiver

  • Full IQ 24 bit data – up to 160 dB dynamic
  • SNR: 126dB at 38kHz, 120dB at 600kHz
  • Different adaptive gains for water column and bottom simultaneously

Marport will be carrying out additional sea trials over the summer months and plans commercial availability for the Multimode Sonar Transceiver by early September, 2009.
