Title:

Development of an Acoustic Propagation Simulator for Shallow
Water Environments

Requirement:

Unmanned systems and off-board sensors are becoming a critical
part of the Canadian Forces toolbox to keep troops out of harm's
way. Even though such systems have gained in autonomy, they
still have limited capabilities for collaborating among
themselves and with other fixed or mobile assets. One particular
area where significant progress is needed is that of underwater
sensor networks. The main impediment to such progress relates to
the unreliable nature of underwater acoustic communications. The
purpose of this contract is to perform research leading to the
development of an acoustic propagation simulator specific to
shallow water environments. 

This contract has the following objectives:
(a)	Investigation of the impact of a layered water current
profile on impulse responses, Doppler spreads and delay spreads.
An assessment of the impact of a layered water current profile
compared to other factors, including sea-surface roughness,
shall be performed for a limited number of shallow water
environments.
(b)	If a significant impact results from the presence of a
layered water current profile, then a physics-based
range-dependent ray-tracing simulator shall be developed and
shall incorporate such a layered water current profile. The
simulator shall also incorporate the effects of sea-surface
roughness. The impact of a partial, complete and rough
underwater-surface ice covers should also be investigated, if
possible.
(c)	Generation and characterization of acoustic channel impulse
responses, Doppler spreads and delay spreads in response to
various shallow water environmental and communication conditions.
(d)	Development of front and back ends of the range-dependent
ray-tracing simulator so that the propagation of complex
broadband acoustic signals can be simulated. If possible, a
hardware-in-the-loop bench system should be built and include
the range-dependent simulator, the front and back ends, as well
as hardware provided by the Project Authority. The
hardware-in-the-loop bench should operate as an overall system
and be capable of taking any user-defined message as an input.
