OBJECTIVE: Develop a
high-bandwidth modem for Next Generation Towed Arrays that meets bandwidth,
form factor, power consumption, and environmental operating requirements.
DESCRIPTION: Next Generation
Towed Arrays will increase mission capability and provide improved acoustic
capability with innovative sensors such as multi-axis accelerometers capable of
providing instantaneous Left and Right ambiguity resolution and increased array
bandwidth. This will provide full spectrum coverage with a single line array
vice multiple arrays. Implementing a new modem provides the increased bandwidth
to the submarine signal path without the need for a fiber optic signal path.
This is a significant reduction in acquisition costs in comparison to
overhauling the entire submarine signal path to fiber optics. A signal path
overhaul of the submarine Fleet would require tens to hundreds of millions of
dollars. The Next Generation Towed Arrays will have significant production potential.
Current commercial modems do not meet requirements for Next Generation Towed
Arrays. A successful solution requires an innovative approach that will meet
the design requirements for Next Generation Towed Arrays. Next Generation Towed
Arrays will need to pass bidirectional data between the arrays and shipboard
array receivers. This will require a high-bandwidth modem. Current towed arrays
modems use a transmission path of 200 to >4000 feet of 50ohm cable between
the array and the array receiver. This signal path has a number of connections
where the impedance is not controlled, which can alter the signal integrity. A
successful solution would be able to transmit with impedances that are not
controlled. Current array modems use bandwidths up to 50 Mbps. Future arrays
modems will use this same signal path but will be required to be scalable in
transmitting up to 225 Mbps.
In addition to data transmission requirements, the new modem needs to meet thin
line towed array environmental form factors (such as temperature, pressure
related to depth, and seawater corrosion) and power consumption requirements.
This will require the modem to fit into a 0.75-inch diameter cylinder with a
length of 5.25-inches and consume less than 5W of average power. The modem
will be required to operate at industrial temperature ranges and a pressure up
to 1125 psig. The modem must be able to survive at pressures up to 2,500 pounds
per square inch, gauge (psig). The Navy will benefit from a high-bandwidth
modem to support improved acoustic capability provided to the submarine fleet
in the Next Generation Towed Array program.
The Phase II effort will likely require secure access, and NAVSEA will process
the DD254 to support the contractor for personnel and facility certification
for secure access. The Phase I effort will not require access to classified
information. If need be, data of the same level of complexity as secured data
will be provided to support Phase I work.
Work produced in Phase II may become classified. Note: The prospective
contractor(s) must be U.S. Owned and Operated with no Foreign Influence as
defined by DOD 5220.22-M, National Industrial Security Program Operating
Manual, unless acceptable mitigating procedures can and have been implemented
and approved by the Defense Security Service (DSS). The selected contractor
and/or subcontractor must be able to acquire and maintain a secret level
facility and Personnel Security Clearances, in order to perform on advanced
phases of this contract as set forth by DSS and NAVSEA in order to gain access
to classified information pertaining to the national defense of the United
States and its allies; this will be an inherent requirement. The selected
company will be required to safeguard classified material IAW DoD 5220.22-M
during the advance phases of this contract.
PHASE I: Develop a concept
for a high-bandwidth modem for Next Generation Towed Arrays that must show that
the modem can feasibly meet the requirements in the description. Establish the
feasibility through analysis and modeling of the technology. The Phase I
Option, if awarded, will include the initial design specifications and
capabilities description to build a prototype in Phase II. Develop a Phase II
PHASE II: Based on the
results of the Phase I and the Phase II Statement of Work (SOW), design,
develop, and deliver a prototype high-bandwidth modem that clearly demonstrates
that it meets the parameters in the description. The Navy will conduct
independent functionality and environmental testing of the prototype.
Demonstration will take place at a Government-provided facility. Prepare a
Phase III development plan to transition the technology for Navy production and
potential commercial use.
It is probable that the work under this effort will be classified under Phase
II (see Description section for details).
PHASE III DUAL USE
APPLICATIONS: Assist the Government in transitioning the high-bandwidth modem
for Next Generation Towed Arrays for Navy use within a Towed Array for the
submarine fleet to allow for further experimentation and refinement. The
implementation of the modem will integrate Towed Array components with the
modem components to show a fully functional modem.
A high-bandwidth Towed Array modem would be of great interest to the seismic
oil exploration industry. It would support development of higher fidelity
seismic arrays and improve beamforming/processing capability. Current arrays
do not require a modem but will likely require one in the future. These
high-fidelity arrays would increase survey speeds (and thus reduce costs) for
sub-bottom mapping in oil exploration and other water-borne geophysical
