SYSTEM DESIGN SPECIFICATIONS FOR A WIDE BAND HIGH
RESOLUTION ECHO SOUNDER SYSTEM
The University of Southern Mississippi
Prepared by Steve Stanic and Landry Bernard
May 1/2026

SYSTEM DESIGN SPECIFICATIONS FOR A WIDE BAND HIGH-RESOLUTION
ECHO SOUNDER SYSTEM
I. Background
The University of Southern Mississippi (USM) has received funding to purchase a wideband
high-resolution echo sounder (WBES). This system will routinely be deployed from one of
USM's survey vessels. This system will be used to map and classify the bottom sediments, fish
habitats, and surface backscattering characteristics as a function of frequency. It will also be used
for the detection, classification, and localization (DCL) of low/medium/high target strength
targets over a broad range of environmental and platform noise conditions.
II. Purpose
This document contains the minimum requirements for a WBES system.
III. General Requirements
1. The WBES shall have three system components, two transmit and receiving split-beam
sonar transducers (one high and one lower in frequency), and a system controller with
acquisition and data processing software.
2. The system shall support multi frequency target detection, classification, and
localization (DCL) in various operating environments
3. The system shall provide calibrated bottom backscattering data.
4. The system shall be able to operate at least 4 individual channels
5. The system shall support the use of multiple displays
6. The system shall be capable of integrating with positioning sensor data for
georeferencing acquisitions.
7. The vendor shall provide a list and the cost of all optional spares
8. The delivery arrangements and transportation costs shall be the vendor's responsibility.
9. The side can sonar systems shall be delivered to USM's Marine
Research Center, 1030 30th Ave Gulfport, MS 39501.
IV. Specific WBES Technical Specifications
The following tables outline the minimum specifications that the WBES system shall meet to
perform the tasks necessary to satisfy USM's project objectives.

V. Specific WBES software requirements.
1. The vendor shall provide software for the operation and control of both split beam and
single beam transducers.
2. The software shall be designed to ensure optimum system performance.
3. The software shall provide diagnostic analysis plots.
4. The software shall have dedicated calibration module with full calibration capabilities.
5. The software shall also have a wideband frequency mode with added processing for
seabed mapping, sediment acoustic response, and water column backscattering analysis.
6. The software shall provide complex target analysis.
2

7. The software shall provide access to raw data files via a network interface.
8. The software shall control the transmission of numerous different frequencies within the
system bandwidth.
9. The software shall be able to display both single and split beam transducer data.
10. The vendor shall provide complete software package (backup) and product
documentation for the WBES system.
VI. Training
The vendor shall provide training on the operation, maintenance, troubleshooting, and
integration of all systems. This must include mission planning and basic mission data
analysis and display. This training shall take place at the USM facility located in
Gulfport MS.
VII. Proof of Performance
The vendor shall provide a proven record of the WBES measurements and operating
system performance. The vendor needs to provide references where these systems and
their operating system in a similar configuration as specified above have operated
successfully within the last 3 years. The above requested information will assist USM in
determining the bidder's capability of meeting these requirements.
VIII. Warranty Services
At a minimum, the contractor shall provide software/hardware warranty support for one
year from acceptance. Longer warranty periods are preferred. The Vendor shall agree to
repair, adjust, and/or replace (as determined by the University to be in its best interest)
any defective materials at the Vendor and/or manufacturers' sole cost. The University
will incur no costs for service or replacement of materials during the warranty period.
The Vendor will be the sole point of contact for warranty issues.
IX. Documentation
The Contractor shall provide Operations and Maintenance manuals to USM.
Documentation provided shall include, but not be limited to the following:
A. Theory of operation
B. Operating procedures
C. Interfacing instructions with connector pin outs
D. Troubleshooting and maintenance procedures
E. IPB (Isometric Parts Breakout) drawings showing how all parts, especially
mechanical parts, relate to one another.
F. Documentation of the various software packages.
G. All sensor documentation and manuals.
