8. Anexo Técnico / Technical Addendum
8.1. Resumo do projecto
Este projecto tem por objectivos fundamentais o desenvolvimento e a validação de sistemas acústicos
de
monitorização remota e de métodos de inversão para monitorizar de maneira segura e eficiente áreas
da zona costeira. Um dos aspectos mais promissores da monitorização ambiental consiste na
utilização duma distribuição de boias acústicas, postas no mar com ajuda de meios navais ou aéreos,
as quais recebem o sinal emitido por uma fonte controlada ou por fontes não cooperantes. Os dados
acústicos recebidos são enviados via rádio para o respectivo navio ou avião, onde são processados para
determinar as características espaciais da coluna de água e as características geológicas do fundo na
área limitada
pela distribuição de boias à deriva. Os parâmetros ambientais obtidos, integrados com dados
oceanográficos medidos directamente, podem ser usados para inicializar e calibrar modelos
oceanográficos de predição para a prevenção imediata ou futura de situações de emergência. A
presente proposta de investigação vem no seguimento dos esforçoes previamente desenvolvidos pela
Universidade de Bruxelas e pelo Centro de Investigação SACLANT para o desenvolvimento de técnicas
de inversão geoacústica com distribuições aleatórias de boias acústicas, conjuntamente com os
estudos desenvolvidos pela Universidade do Algarve em que foi testada experimentalmente a tomografia
acústica oceanográfica com fontes não-cooperantes. Em particular, conceitos provados em condições
estáticas, tais como a utilização de sinais codificados de banda larga propagando-se entre um único par
fonte-sensor [1], ou entre um sistema fonte - antena de sensores [2], serão extendidos ao caso da
configuração dinâmica de boias acústicas deixadas à deriva.
8.2. Project's summary
This research project aims at the development and validation of acoustic remote sensing systems and
inversion methods for the reliable, rapid environmental assessment (REA) of shallow water areas. One of
the most promising REA concepts is to use a field of sonobuoys, deployed either from the air or from a
surface ship, to receive signals from a controlled sound source or sources of opportunity. The acoustic
data, radio telemetered to the aircraft or ship, are processed to determine the range-dependent,
water-column and bottom acoustic properties over the area spanned by the drifting buoys.
The resulting environmental parameters integrated with concurrent oceanographic measurements are
then used to initialize and calibrate oceanographic prediction models for nowcast and forecast
environmental hazards in potential areas. The proposed research work directly stems from previous
efforts carried at University the Bruxelles and at SACLANT Undersea Research Center for geoacoustic
inversion techniques with random fields of sonobouys and at University of Algarve, in the context of
experimental testing of ocean acoustic tomography with sources of opportunity. In particular, proved
concepts under static conditions, such as the use of a broadband coded signal propagated between a
single sound source and a single hydrophone [1] or a fixed array of hydrophones [2], will be extended to
the dynamic configuration of freely drifting sonobuoys.
8.3. Descrição do projecto (Project's Description)
8.3.1. Objectivos (Objectives)
To develop: (a) data-oriented segmentation and inversion algorithms for range-dependent, geoacoustic
mapping and seabed characterization; (b) optimization algorithms for environmental focusing and
water-column parameter estimation from the acoustic field received from non-cooperating sources on a
random field of sonobuoys; (c) integration of on-site simultaneously measured oceanographic data as
apriori information to constrain the tomographic inversion; (d) investigation of stochastic approaches to
the signal processing and propagation modeling supporting the inversion of broadband acoustic signals;
(e) study of sensitivity to bottom parameters and robustness against oceanographic and acoustic
variability using existing SACLANTCEN datasets collected under diverse conditions; (f) at-sea validation
under complex environmental conditions and concluding on the capabilities and limitations of the
proposed methods and their applicability under realistic at-sea operations.
8.3.2. O Projecto e os objectivos do IR a longo prazo
(The project and the long term objectives of the PI)
The Project Leader (PL) of RADAR has a significant experience in the field of underwater acoustics for
more than 16 years. First at SACLANTCEN, where he was involved with early studies in matched-field
processing (MFP), and then at UALG where continued is research on MFP but including the estimation
of
environmental parameters: geoacoustic parameters in MAST project (1993-1996), internal tides during
project INTIMATE (1997-2000) and water temperature in ATOMS (2000-2003). The PL is coordinating the
SIPLAB laboratory (www.ualg.pt/fet/adeec/siplab), as part of the ISR-Lisbon, and developing a consistent
know-how in marine technology under the frame of the ISR Associate Laboratory (Theme A). The
collaboration proposed under RADAR with ULB (Belgium) and SACLANTCEN (Italy) would greatly
contribute to the strengthening of the international connections of SIPLAB.
8.3.3. Repercussões éticas, sociais e ambientais (Ethic, social and environment impacts)
All the knowledge about the structure of the Portuguese coast assumes strong importance in coastal
management and prevention in the case of natural or man induced hazards. There is a direct relationship
with marine resources, fisheries exploitation and management, with the protection of structures like
bridges, ports, seashore line and with the study of complex processes like beach erosion, sediment
transport, surface and internal tide propagation and currents. Their impact on country economy and
population welfare is certain. An acoustic monitoring system can provide an efficient tool for the real-time
assessment of the environment. The experiments under this proposal will be carried out at sound levels
well below those produced by the ship traffic crossing the area under study, making possible to preserve
a noise free ambient for the marine mammals.
8.3.4. Relação com o estado da arte (Relationship with the state of the art)
Modern approaches to detect, locate and classify oceanographic features require an accurate
time-varying environmental description of the area. One important aspect in obtaining such description is
the coherent integration of directly measured oceanographic data and indirectly estimated environmental
parameters from various remote sources such as satellite and resulting from the inversion of acoustic
data. In contrast with deep water propagation, in shallow water the sound field is dominated by guided
waves. Guided waves are mostly determined by boundary conditions. Therefore, the overall structure of
the channel response is not very sensitive to "small" variations of the sound speed profile. Conversely,
the received field is extremely dependent from the acoustic properties of the sea bottom. These two
complementary aspects -water column sound speed estimation and geoacoustic inversion- will be
discussed below. Previous shallow water tomography experimental results were obtained with vertical
arrays and coded signals (M-sequences, [3]), LFM chirps and multiple vertical arrays for internal wave
activity estimation (SWARM experiment, [4]) and for internal tide estimation on the continental shelf
(INTIMATE experiment, [5-7]). Most of these studies used techniques derived from deep water
tomography, based on travel time identification and correlation with ray tracing model predictions. There
are two important drawbacks in both approaches: first, actual ray tracing models do not exactly account
for complex bottom structures and, second, acoustic paths dominated by waterborne waves have very
close and unstable arrival times, difficult to identify and track. Thus, a promising alternative appears is to
join large time-bandwidth signals ([1,2]) with matched-field tomography approaches, making possible to
resolve closely spaced arrivals and not requiring arrival-time identification. Recent studies have reported
experimental preliminary results demonstrating the feasibility of shallow water tomographic inversion with
non-cooperative sources, navigating at ranges and depths unknown at the receiver, over range dependent
and range-independent shallow water areas. The transmitted signals were broadband LFM chirps and
pseudo-random noise ([8,9]) and actual ship noise along another event ([2,9]). The integration of
oceanographic and inverted acoustic data can be achieved by introducing actual physical constraints on
the temperature field, thus allowing a substantial reduction of the search space and decreasing the
variance of the final estimate. Such oceanographic data can be under the form of water column
temperature data, gathered by appropriate low cost sensors, co-located with the acoustic receivers,
and/or sea surface temperature measurements from satellite surveying of the experimental area.
Geoacoustic inversion in a shallow water environment seek to exploit the spatial structure of water-borne
pressure.

8.4.8. Sumário de projectos anteriores (Abstracts of previous projects)
The objective of this project is to develop the concept of a towed remote sensing acoustic instrument
being able to conduct high-resolution measurements of the geo-physical properties of the seafloor in
shallow water and coastal areas. The research under the proposed project will study the optimal
configuration and mode operation of a towed hydrophone array for the specified task and will develop
suitable inversion algorithms for estimation of the geophysical structure of the seabottom and
subbottom. An experimental device will be assembled and its performance evaluated at sea. The study
will involve theoretical knowledge and original developments on the fields of array processing, acoustic
propagation with boundary interaction, propagation in layered media and data inversion techniques. The
actual state of the art in the field let us expect that the concept to be devloped will provide insight for
direct implementation of a commercial device with a range of applications.

Acoustics is one of the main tools for ocean exploration. Inspired from biomedical engineering, ocean
acoustic tomography consists in using one or more acoustic sensors/sources, strategically distributed
in
a water volume and simultaneously emitting and receiving coded signals. "Comparing" emitted and
received signals allows to characterize the environment between source(s) and receiver(s). In the
continental shelf, internal tides are extremely important for coastal dynamics, with in particular close to
the shelf break and topographic irregularities like sea canyons. This project aims at proving the concept
of using vertical arrays of sensors and acoustic sources for the tomographic estimation of oceanographic
internal-tide characteristics on the continental shelf, and coastal waters. During the project it will be
selected areas of interest near the Portuguese coast for testing and further validation of tomographic
results with ground truth measurements.

The objectives of this project is to implement new and extend existing capabilities of the underwater
vehicle MARIUS. MARIUS is a remotely operated underwater vehicle that was built under European
programme MAST I and II on consecutive projects leaded by IST. Under INFANTE, it is forseen to
replace MARIUS hull, improve the guidance system and develop new technologies for ship-vehicle
underwater communication thus extending its capabilities. One at-sea test is forseen to take place from
12 to 16 July 1999 in a shallow water off the coast of Portugal. Underwater acoustic communication
systems will be tested and environmental data will be gathering for offline processing of acoustic data.
