The Synthetic Aperture Radar (SAR) is a microwave active imaging radar that, due to its all- day and almost all-weather observation abilities together with a fine-to-moderate spatial resolution, is a very versatile remote sensing instrument for regional-scale applications. Nowadays, there is an increasing trend in the number of conventional or small satellite scientific and commercial missions equipped with very high-performance SARs operating in a range of frequencies that span from P-band up to K-band and capable of performing both intensity-only and polarimetric measurements. This means that the huge amount of SAR measurements collected (especially in coastal areas) calls for robust and effective models and methods to generate added value products.
This full-day tutorial is to describe the leading-edge methodologies and the underpinning physical rationale to generate multi-polarization SAR added-value products for coastal area applications complementing the subjects addressed by Technical Session Topics 4 and 6. Selected topics will be addressed both theoretically and experimentally (i.e., showcased on real SAR measurements). First, preliminary analysis will be carried on multi-polarization SAR imagery to gain familiarity with basic concepts of speckle filtering, speckle statistics, Pauli RGB decomposition, etc. Then, advance methods will be showcased focusing on selected applications, namely sea surface pollution monitoring, ship/target detection and coastline extraction).

T5 | 9.30-12.30 | Introduction to LSTS Toolchain: Bridging interoperability challenges
Presenters: Paulo Dias, João Costa, Ricardo Santos, João Borges de Sousa, LSTS , Portugal
Session Length: Half day
Requirements for attendees: Not specified.
The LSTS control architecture has an off-board component and an on-board component. These are implemented with the help of the LSTS Neptus-IMC-Dune software toolchain. This is a software framework for mixed-initiative command and control (humans in the planning and control loops) of unmanned underwater, surface, and aerial vehicles. These unique toolchain features build on experience with the coordinated operation of heterogeneous vehicles.
Neptus is a distributed command, control, communications and intelligence framework for operations with networked vehicles, systems, and human operators. Neptus supports all the phases of a mission life cycle: world representation; planning; simulation; and, execution, and post-mission analysis. IMC is a communications protocol that defines a common control message set understood by all LSTS nodes (vehicles, consoles, or sensors) in networked environments. This provides for standard coupling of heterogeneous components in terms of data interchange. DUNE is the vehicle’s on-board software. It is used to write generic embedded software at the heart of the vehicle, e.g., code for control, navigation, or to access sensors and actuators. It provides an operating-system and architecture-independent C++ programming environment for modularly writing efficient real-time reactive tasks.
In this tutorial, we will showcase the LSTS Toolchain, a set of software tools developed at the University of Porto by the Underwater Systems and Technology Lab (LSTS) to control, plan, monitor, and supervise teams of heterogeneous vehicles in communication-challenged environments. In this session, an overview of the main components of the toolchain will be given, and a demonstration of how to use it will take place. This session will also give a Neptus overview and demonstrate how new vehicles can be integrated into a multi-vehicle system by exposing capabilities and performing the assigned behaviors.

Presenters: Shayla Fitzsimmons, Jeff Cullis, CIOOS Atlantic, Halifax
Session Length: Half day
Requirements for attendees: Participants should have their own laptops or tablet.
To ensure all participants have been introduced to the same suite of data management concepts, a brief introduction will provide background, along with those terms and principles which form the foundation of data management activities. The importance of data management will be reiterated and reinforced, with specific focus on open versus restricted data and the FAIR, CARE, and TRUST principles. The majority of the tutorial will focus on management of metadata and data, with participants invited to use a provided dataset or to bring a dataset from their own research on which to work. (As this tutorial will focus on physical and biochemical data, we would ask that the ocean observation data in self-provided datasets fall within these parameters.) The ISO 19115 metadata standard will be introduced and applied along with the Climate and Forecast metadata and data conventions. Utilizing the Canadian Integrated Ocean Observing System (CIOOS) metadata profile and data standards as an exemplar, participants will be guided through the creation of a metadata profile based on the ISO 19115 standard. This profile was developed through collaboration with some of the foremost experts on ocean data management in Canada, and applies national and international best practices. Participants will also be guided through application of the commonly-used Climate and Forecast conventions.
Presenters will be available for one-on-one feedback and assistance during the hands-on portions of the tutorial, each of which will be preceded by short presentations that provide supplementary information, including tips and best practices, to guide participants through the process. Participants will also be encouraged to ask questions and share knowledge amongst themselves. The tutorial will begin with an icebreaker activity to encourage networking and to facilitate this increased knowledge exchange.

Session Length: Half day (workshop)
Requirements for attendees: Not specified.
The objective of this workshop is to share and explore new frontiers and technologies in the field of autonomous underwater vehicle navigation using model-based approaches and novel learning methods.
In this workshop we aim to present novel model and learning based methods for INS/DVL fusion and address solutions for robust and accurate navigation in three possible fusion scenarios pending DVL measurement availability: 1) complete measurements (normal conditions), 2) partial measurements, and 3) no measurements (DVL outages).
The workshop will include the following topics:
- Prof. Itzik Klein, Model-based INS/DVL fusion in situations of complete/partial DVL measurements
- Prof. Itzik Klein, ProNet: A hybrid adaptive velocity aided navigation filter
- Kobi Libero (PhD student), A multiple inertial measurement unit filter for AUV navigation
- Nadav Cohen (PhD student), Data-driven approaches enhancing DVL velocity vector solution
Prof. Itzik Klein received B.Sc. and M.Sc. degrees in Aerospace Engineering from the Technion - Israel Institute of Technology, Haifa, Israel, in 2004 and 2007, respectively, and a Ph.D. degree in Geo-information Engineering from the Technion - Israel Institute of Technology, in 2011. He is currently an Assistant Professor, heading the Autonomous Navigation and Sensor Fusion Lab, at the Hatter Department of Marine Technologies, University of Haifa. Itzik serves as an IEEE Senior Member and has exceptional experience in navigation systems and sensor fusion. Prior to joining the University of Haifa, he worked at leading companies in Israel on navigation topics for more than 15 years. Among the areas of his research are the intersection of artificial intelligence with navigation and sensor fusion in order to protect oceans and the environment, as well as developing tools for autonomous vehicle teamwork.
