A field-based method for evaluating thermal properties of static and mobile camouflage
(2018)
Reliable and realistic methods for assessment of thermal infrared signature properties for military purposes are important. With a basis in ongoing developments of imaging technologies, especially towards mass markets, ...
Tactical Router Interoperability: Concepts and Experiments
(2018)
Interoperability on the lower tactical levels, e.g. in a multinational battalion or team, poses challenges because of the high degree of mobility and limited data capacity at the tactical edge. Enabling such multi-national ...
Measurement of point spread function for characterization of coregistration and resolution: Comparison of two commercial hyperspectral cameras
(2018)
For spectral cameras, the spatial resolution and coregistration of bands are important performance characteristics. The paper discusses how these can be quantified in a way that is relevant for the spectroscopic processing ...
Field-Testing of High-Level Decentralized Controllers for a Multi-Function Drone Swarm
(2018)
This paper describes the results of initial field testing of a high-level decentralized controller for a swarm of multi-rotor drones. This controller allows the intuitive implementation of a wide variety of swarm behaviors. ...
A New Distributed Localization Algorithm Using Social Learning Based Particle Swarm Optimization for Internet of Things
(2018)
Emerging applications in the Internet of Things (IoT) will depend on the accurate location of thousands of deployed sensors. However, accurate localization of deployed sensors nodes is a classical optimization problem which ...
Hierarchical path planning for walking (almost) anywhere
(2018)
Computerized path planning, not constrained to transportation networks, may be useful in a range of settings, from search and rescue to archaeology. This paper develops a method for general path planning intended to work ...
Image-aided inertial navigation for an Octocopter
(2018)
A typical unmanned aerial system combines an Inertial Navigation System (INS) and a Global Navigation Satellite System (GNSS) for navigation. When the GNSS signal is unavailable, the INS errors grow over time and eventually ...
Characterization of in-field additively manufactured polymer composites – hot and dusty environment
(2018-05-09)
As part of the European Defence Agency (EDA) Operational Budget (OB) study “Additive
Manufacturing Feasibility Study & Technology Demonstration” (EDA contract no.
16.ESI.OP.144), in-field 3D printing of objects, i.e. ...
SAR ship detection in dual polarization combination channels
(2018-05-16)
Satellite Synthetic Aperture Radar (SAR) imagery is widely used for automatic ship detection.
SAR data comes in different modes and polarization combinations. Dual polarization ScanSAR
products offer good spatial coverage, ...
Non-destructive testing of graphene/epoxy composites using terahertz waves
(2018-10-18)
Earlier experiments have shown that composites that include carbon fibers can exhibit
significant transmission of Terahertz (THz) waves, in spite of the good electrical conductivity of
carbon fibers. This observation ...
