VErsatile RAdar – RFSoC based radar demonstrator for multiple applications
(2022-10-04)The Norwegian Defence Research Establishment (FFI) VeRa (Versatile Radar) is a radar demonstrator for multiple applications based on the 1st generation Xilinx RF System on Chip (RFSoC). This paper describes the hardware ... -
Can the absolute configuration of cyclic peptides be determined with vibrational circular dichroism?
(2023-05-16)Cyclic peptides show a wide range of biological activities, among others as antibacterial agents. These peptides are often large and flexible with multiple chiral centers. The determination of the stereochemistry of molecules ... -
Adaptive phase estimation filter in long range synthetic aperture sonar interferometry
(2023-05-15)Synthetic aperture sonar (SAS) interferometry is a technique for very high resolution imaging and mapping of the seabed. In SAS interferometry, the seabed depth estimation performance is a function of the system, the ... -
High-Resolution Neural Network Processing of LFM Radar Pulses
(2023-05-05)In radar applications, the bandwidth of a transmitted pulse determines the range resolution and the ability to disclose densely spaced targets. The processing of radar signals is often carried out through matched filtering ... -
The malleability of competitive preferences
(2023-04-14)Men are more competitive than women, but we do not know how stable competitive preferences are. We conduct a pre-registered data collection in the Norwegian Armed Forces, a traditionally male environment, using survey ... -
Band structures and Z2 invariants of two-dimensional transition metal dichalcogenide monolayers from fully relativistic Dirac-Kohn-Sham theory using Gaussian-type orbitals
(2023-06-02)Two-dimensional (2D) materials exhibit a wide range of remarkable phenomena, many of which owe their existence to the relativistic spin-orbit coupling (SOC) effects. To understand and predict properties of materials ... -
Point detection in textured ultrasound images
(2023-02-26)Detection of point scatterers in textured ultrasound images can be challenging. This paper investigates how four multilook methods can improve the detection. We analyze many images with known point scatterer locations and ... -
Introducing the Jihadi Plots in EuropeDataset (JPED)
(2023-02-21)The article introduces a new dataset on terrorist attack activity by jihadis in Western Europe. The dataset was built over nearly two decades at the Norwegian Defence Research Establishment. It records not only attacks ... -
Radio-Frequency Interference Considerations for Utility of the Galileo E6 Signal Based on Long-Term Monitoring by ARFIDAAS
(2023)The extent to which navigation signals in the E6 band may be impacted by shared spectrum allocations might be underappreciated. This paper presents top-level observations from a multi-year international radio frequency ... -
Command and control in a fifth generation Air Force: Coordination requirements of air operations with F-35 and the command and control-System of the Norwegian Armed Forces
(2022)This article discusses the ways in which the F-35 Lightning aircraft might affect the command and control (C2) of the Royal Norwegian Air Force. It emphasises the importance of coordination answering questions regarding ... -
HYPSO-1 CubeSat: First Images and In-Orbit Characterization
(2023-01-28)The HYPSO-1 satellite, a 6U CubeSat carrying a hyperspectral imager, was launched on 13 January 2022, with the Goal of imaging ocean color in support of marine research. This article describes the development and current ... -
The Space of Influence: Developing a New Method to Conceptualise Foreign Information Manipulation and Interference on Social Media
(2023-05)Foreign information manipulation and interference (FIMI) on social media is a fast- evolving threat to democracies. However, there is a growing need to systematically conceptualise the phenomenon. General Morphological ... -
Using Low-Cost Radar Sensors and Action Cameras to Measure Inter-Vehicle Distances in Real-World Truck Platooning
(2023-05-06)Many modern vehicles collect inter-vehicle distance data from radar sensors as input to driver assistance systems. However, vehicle manufacturers often use proprietary algorithms to conceal the collected data, making them ... -
Under-ice mid-frequency acoustic transmissionand communication in two Arctic Oceanenvironments
(2023-02-23)This paper presents data from mid-frequency (4−8 kHz) under-ice acoustic transmission and communication experiments in the Nansen Basin and in the Beaufort Sea of the Arctic Ocean. Measured impulse responses to range ~10 ... -
Wind- and tidal driven ambient noise in seasonallyice-covered waters north of the Svalbard archipelago
(2022-08-24)This paper presents analysis of a 1-year (2018–2019) recording of ambient noise (40–2000 Hz) at a seasonally ice-covered location on the continental slope between the Svalbard archipelago and the Nansen Basin, northeast ... -
Towards data-driven autonomous cyber defence for military unmanned vehicles - threats & attacks
(2022-11-28)Unmanned vehicles with varying degrees of autonomy will likely change the way military operations can be conducted, but they also introduce risks that require new ways of thinking security. In particular, the safety ... -
Towards XAI in the SOC – a user centric study of explainable alerts with SHAP and LIME
(2023-01-26)Many studies of the adoption of machine learning (ML) in Security Operation Centres (SOCs) have pointed to a lack of transparency and explanation – and thus trust – as a barrier to ML adoption, and have suggested ... -
LADEMU: a modular & continuous approach for generating labelled APT datasets from emulations
