Classification based on fast and robust approximations to order statistics
(2020-04-22)A test system with four cameras in the infrared and visual spectra is under development at FFI (The Norwegian Defence Research Establishment). The system may be mounted on a jet aircraft or may be used in a land-based ... -
Classification of acoustically stable areas using empirical orthogonal functions - examination of stability methods
(2011-11-08)Overview and control of the oceanographic and acoustic variations are very important in underwater warfare. We have developed a method for dividing an area into smaller subareas that can be represented by a single vertical ... -
Classification of birds and UAVs based on radar polarimetry
(2016)This letter aims to show the potential of using polarimetric parameters to distinguish between large birds and unmanned aerial vehicles (UAVs) of comparable size in the context of a modern long-range air defense radar. ... -
Classification of Ships Using Real and Simulated Data in a Convolutional Neural Network
(2016)Convolutional neural networks (CNNs) have recently been applied successfully in large scale image classification competitions for photographs found on the Internet. As our brains are able to recognize objects in the images, ... -
Clostridium botulinum Group I Strain Genotyping by 15-Locus Multilocus Variable-Number Tandem-Repeat Analysis
(2011)Clostridium botulinum is a taxonomic designation that encompasses a broad variety of spore-forming, Gram-positive bacteria producing the botulinum neurotoxin (BoNT). C. botulinum is the etiologic agent of botulism, a rare ... -
Cloud influence on maritime surveillance by an optical satellite
(2016-03-03)Disturbing clouds may be a showstopper when planning a maritime surveillance satellite with an optical sensor. When the probability of clouds in any place is in the range of 75 %, it is indeed important to know where the ... -
Cloud-based decision support system for planning military operations
(2020-02-21)When planning a military operation, it is important to explore possibilities and understand consequences of the plan. To this end, wargaming can be used for assessing possible courses of action (COA) for own and enemy ... -
A Cloud-based experimentation and analysis framework for services at the tactical edge
(2022-09-22)In this paper we present an experimentation and analysis framework that utilizes a public cloud infrastructure for most of the experimentation environment but also supports interaction with services installed on servers ... -
Cluster weapons - military utility and alternatives
(2008)This report is made through the sponsorship of the Royal Norwegian Ministry of Foreign Affairs. Its purpose is to get an overview of the military utility of cluster munitions, and to find to which degree their capacity ... -
Clustering evaluation for deinterleaving
(2013-02-23)Deinterleaving is a fundamental step in a lot of processing in ESM and radar systems, enabling users and/or client programs to focus on data from a single emitter at a time, rather than a mixture of data from several ... -
Coherent high-speed acoustic communication inside a commercial atlantic salmon pen
(2020-06-07)Fish telemetry is a potential method to monitor the well-being of farmed fish, where a reference group of fish are equipped with sensors tags that oversee their health and wirelessly transmit the data. Many fish must be ... -
Coherent range and Doppler-walk compensation in PBR applications
(2014)The focus of PBR research has shifted from FM to also include DVB-T and DAB over the last years, and are facing the challenges of higher bandwidth, i.e. improved range resolution. While the FM based PBR systems primarily ... -
A collection of oceanographic and geoacoustical data in Vestfjorden - obtained from the MILOC survey Rocky Road
(2002)A brief overview of oceanographic and geoacoustic data from the Vestfjorden area is given. The overview is based on data collected during the MILOC survey Rocky Road, which took place during 1992-95. -
Colliding Pulse Mode Locking and Nonequilibrium Carrier Dynamics within Vertical External-Cavity Surface-Emitting Lasers
(2022-08-02)The complex nonlinear dynamics of colliding counterpropagating ultrashort laser pulses circulating in a vertical external-cavity surface-emitting ring laser cavity are captured by a first-principles quantum-mechanical ... -
Collision Avoidance for Underactuated Marine Vehicles Using the Constant Avoidance Angle Algorithm
(2019-03-21)Avoiding collisions is a crucial ability for unmanned vehicles. In this paper, we present the constant avoidance angle algorithm, a reactive method for collision avoidance. It can be used to avoid both static and moving ... -
Collision Avoidance for Underactuated Surface Vehicles in the Presence of Ocean Currents
(2022-11-29)This paper considers the problem of collision avoidance for surface vehicles moving under the influence of ocean currents. The vehicles we consider have underactuated dynamics, where the vehicle cannot directly control its ... -
Combination of stereo SAR and InSAR for DEM generation using TanDEM-X spotlight data
(2017)The objective of this work is to generate accurate digital elevation models (DEMs) from synthetic aperture radar (SAR) interferograms using the spotlight and staring spotlight modes during the TanDEM-X (TDX) science phase. ... -
Combined range ambiguity resolution and noise reduction in lidar signal processing
(2018)When the interval between transmitted pulses is shorter than the time of flight, it is not straightforward for a lidar to determine the distance uniquely. We present a method that uses varying pulse intervals, constructs ... -
Combustion of RS-41
(2000)The pyrotechnic composition RS-41, a mixture of 49 wt.% KClO4, 49 wt.% Al/Mg and 2 wt.% Calcium Resinate, is an important ingredient in the MP (Multipurpose) ammunition. RS-41 placed in the front of the projectile ignites ...
