This 3-day, classroom and practical instructional program provides individuals or teams entering the unmanned aircraft system (UAS) market with the need to 'hit the ground running'. Delegates will gain a working knowledge of UAS system classification, payloads, sensors, communications and data links. You will learn the UAS weapon design process and UAS system design components. The principles of mission planning systems and human factors design considerations are described. The critical issue of integrating UAS in the NAS is addressed in detail along with major considerations. Multiple roadmaps from all services are used to explain UAS future missions.
ELINT Interception and Analysis course samplerJim Jenkins
The course covers methods to intercept radar and other non-communication signals and a then how to analyze the signals to determine their functions and capabilities. Practical exercises illustrate the principles involved.
Autonomous underwater vehicles (AUVs) often operate close to the seabed (5m-15m) enabling higher resolution surveys using high frequency sonars. Compact Autonomous surface vessels (ASVs) are often deployed in shallow water environments where deeper-draft manned survey vessels are unable to operate. On such vehicles there is limited space to deploy separate imaging, mapping and sub-bottom sonars. This presentation describes the technology deployed in the EdgeTech 2205 sonar system, which enables combined data acquisition in one system on AUVs and ASVs. Examples of the data acquired are given, which can include dual- or triple- frequency side scan, Multiphase Echosounder (MPES) swath bathymetry, and sub-bottom profiler data.
Paco Santana of iRobot explains the current state of art for maritime robotics and the way ahead. The brief can be found here

Teledyne-RESON develops innovative technologies for Offshore, Survey and Dredge markets. This paper explains the latest technologies and applications in which they may be used.
In the presentation the following topics will be explained and shown.
The latest models of SeaBat systems are capable of generating Frequency Modulated pulses for improved depth performance and resolution. This reduces the impact of ambient noise in the water column and results in a more robust detection of the seafloor.
It improves the data significantly minimizing the processing time even further.
Teledyne-RESON has developed an algorithm to automatically detect and track pipelines in the multibeam swath. It outputs the standard 5 points pipeline information in real-time consisting of top of pipe, mean seabed and seabed next to the pipe. The output can be sent to data acquisition and processing software for further analysis, including free-span detection. Pipelines with 40 cm diameter are detected and tracked at a waterdepth of 200 meter.
A further development is to display the real-time water column data in the multibeam display. Water column data reveals items of interest which may be difficult to detect in digitized depths, such as poles, and small details on wrecks. The real-time water column shows the history of the data in the along-track and across-track directions. Water column data may be output to any hydrographic software such as PDS2000 to be further processed.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

The EOID laser line scan technology uses a diode-pumped Nd: YAG laser that provides 500 mW
of power for the Raytheon system and 160 mW for the Northrop Grumman system, both
operating at 532 nm wavelength. The Raytheon system was a research and development
sensor maintained and operated by CSS while the Northrop Grumman system was sized to fit
into the AN/AQS-14A(V1) towed body. The laser illuminates a small spot, which is synchronously
scanned by a photomultiplier receiver to build up a raster-scanned image. The laser scans
downward through a 70-degree field-of-view (FOV). Figure 1 represents the EOID scanning
scheme for target identification.

13. “To acquire the target, Archerfish activates its short range sonar and video link,
transmitting sonar imagery and video pictures back to its controller for inspection
and identification. The advanced maneuvering capabilities enable it to traverse the
target to obtain images from a variety of angles providing the controller with
detailed identification information.
Following confirmation of target, Archerfish is maneuvered in place where the mine
is detonated…”

17. Special Operations (SPECOP) Forces
• Possible Concerns:
-Detection of underwater light sources used by SPECOP forces:
-Light sticks were developed by the U.S. Navy as an inconspicuous and
easily shielded illumination tool for special operations forces dropped
behind enemy lines. Besides their use as children's toys, they are also
used extensively as a navigation aid by divers searching in muddy
water. The light sticks glow as a result of the energy released by a
chemical reaction.

22. Passive Optical Hull & Surface Wake
Detection
Visual Detection
Submarines operating at or near the surface are potentially vulnerable to visual
detection. Anything that protrudes above the surface, such as a periscope,
antenna, or mast will leave a significant wake if the submarine is moving at any
speed over a few knots. And, since depth control and steerage is quite difficult at
low speeds, it is not uncommon for submarines to be traveling at least 4 or 5
knots just below the surface.
The periscope (for example) will create a wake, called "feather", which is quite
visible, and will also leave a remnant of its passage, called a "scar". The scar is a
long streak of foam or bubbles left behind after the object passes. The feather
may be just a few meters, but the scar may be tens of meters long. Either may be
visible for up to 10 miles, and are easily spotted by low flying aircraft in the
vicinity.
Periscopes and other protruding masts and antennas are also often painted in
dark or camouflage colors to reduce their visibility.
If the water is especially clear, the submarine hull or its shadow may be visible for
a few hundred feet under water, but is usually not distinguishable unless the
water is shallow with a light colored bottom (like white sand).

27. Other Possible ASW Applications:
Nighttime Passive Optical Detection due
to Bioluminescence
28. Bioluminescence:
Why Should the Navy Care?
• Complements acoustics - does not replace it
• Prevalent in the acoustically noisy littorals where
boats must operate shallow
• Many initial submarine detections are by non-
acoustics
30. Summary of Concept Demo
on US Submarine
• Photometer successfully collected
Bioluminescence intensity while a USS
Submarine was underway
• Could distinguish night/day Bioluminescence in
signatures, even without validated time stamps
• Could distinguish higher/lower Bioluminescence
based on depth of Submarine
31. What is Bioluminescence:
An optical parameter
• Emission of light by living organisms
• Turbulence initiated chemical reaction
• Globally distributed phenomenon
– est. 70% of marine organisms bioluminesce
– measured from equator to Arctic pack ice
• Blue-green in color which travels furthest
in the ocean

32. UNCLASSIFIED
What causes these
organisms to glow?
Bioluminescent organisms can be
mechanically stimulated to
produce light. Turbulence
generated by a ship’s passage or
even the movement of dolphins
and fish is enough to create the
glow.
UNCLASSIFIED
33. UNCLASSIFIED
Does it matter? Those cells are so small.
The luminescence of a single
dinoflagellate is readily visible
to the dark adapted human eye.
Most dinoflagellates emit about
6 e+8 photons in a flash lasting
only about 0.1 second.
Much larger organisms such as
jellyfish emit about 2 e+11
photons per second for
sometimes tens of seconds.
34. Bioluminescence
You don’t have to be a large target to be vulnerable to
detection by bioluminescence.
Figures show low light level camera detection of a 10 in.
diameter sphere at different depths.
Depth = 10 ft. Depth = 20 ft.
35. Optical Clarity
• The clarity of the water depends on multiple factors
and varies depending on depth, location, currents,
outflow from rivers to name a few factors.
• Objects may be vulnerable due to color and
configuration. If the target has a high contrast
against the background it is more likely to be
spotted.
• In clear, shallow areas where bottom reflectance is
high (e.g., white sand, light colored coral), vertical
(downward) detection of relatively dark objects will
be enhanced due to contrast.

39. Bathymetry from Ocean Color
• Knowledge of ocean bathymetry is important for navigation & for
scientific studies of the ocean's volume, ecology, and circulation, all
of which are related to Earth's climate.
• In coastal regions detailed bathymetric maps are critical for storm
surge modeling, marine power plant planning, understanding of
ecosystem connectivity, coastal management, and change analyses.
• Because ocean areas are enormously large and ship surveys have
limited coverage, adequate bathymetric data are still lacking
throughout the global ocean.
• Satellite altimetry can produce reasonable estimates of bathymetry
for the deep ocean [Sandwell et al., 2003, 2006], but the spatial
resolution is very coarse (∼6–9 kilometers) and can be highly
inaccurate in shallow waters, where gravitational effects are small.
• Depths retrieved from the ETOPO2 bathymetry database for the Great
Bahama Bank are seriously in error when compared with ship
surveys & no statistical correlation was found between the two
• Determining a higher-spatial-resolution (e.g., 300-meter) bathymetry
of this region with ship surveys would require ~ 4 years of nonstop
effort.
