Krigsspill i operasjonsplanlegging: Hva kan datasimuleringer bidra med?
(2022-09-19)Krigsspill er en sentral aktivitet i operasjonsplanlegging for både å utvikle alternative handlemåter og utvikle plan basert på valgt handlemåte. Å gjennomføre krigsspill i et operativt miljø har stramme føringer i forhold ... -
Simulation-Supported Wargaming for Assessing Force Structures
(2022-09-19)Wargaming is a key activity for gaining deeper insight into the strengths and weaknesses of future force structures in the course of their development and assessment. For more than a decade, the Norwegian Defence Research ... -
To Learn or not to Learn: On the Importance of Mode Switching in Educational Wargames
(2022-09-19)Conventional wisdom holds that educational wargames come with certain challenges – factors that can potentially hinder, rather than increase, learning – and that these must be mitigated. In this article, we argue that ... -
Wargaming for the Purpose of Knowledge Development: Lessons Learned from Studying Allied Courses Of Action
(2022-09-19)We present a series of four wargames intended to improve our ability to analyze the alliance aspect of Norwegian military operations. We discuss the objectives, the set-up, and the lessons learned. The wargames proved to ... -
Practical Jamming of a Commercial 5G Radio System at 3.6 GHz
(2022-09-22)Fifth-generation (5G) mobile technology has attracted interest from armed forces worldwide due to its many new possibilities for communication. Military operations may face threats in the electromagnetic spectrum, such as ... -
Freezing Unicast Paths in Sensor Swarms
(2022-09-22)Drone swarms have great potential to convey sensor information. However, a swarm may have a very high degree of topology dynamics. This impedes the sensor data distribution from the sensor node to consumers which are ... -
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 ... -
Jamming and Jamming Mitigation for Selected 5G Military Scenarios
(2022-09-22)This paper presents jamming and jamming mitigation techniques, which can be used in relation to emerging military systems based on fifth-generation (5G) technology. Nowadays, 5G technology provides incremental improvements ... -
Vibrational Corrections to NMR Spin-Spin Coupling Constants from Relativistic Four-Component DFT Calculations
(2022-09-22)Zero-point vibrational (ZPV) corrections to the nuclear spin–spin coupling constants have been calculated using four-component Dirac–Kohn–Sham DFT for H2X (where X = O, S, Se, Te, Po), XH3 (where X = N, P, As, Sb, Bi), and ... -
Multi-gigawatt peak power post-compression in a bulk multi-pass cell at a high repetition rate
(2022-09-27)The output of a 200 kHz, 34 W, 300 fs ytterbium amplifier is compressed to 31 fs with >88% efficiency to reach a peak power of 2.5 GW, which to date is a record for a singlestage bulk multi-pass cell. Despite operation ... -
Compact multimodal multispectral sensor system for tactical reconnaissance
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2022-09-30)Multispectral imaging is an attractive sensing modality for small unmanned aerial vehicles (UAVs) in numerous military and civilian applications such as reconnaissance, target detection, and precision agriculture. Cameras ... -
Interoperable, adaptable, information exchange in NATO coalition operations
(2022-10-01)This paper summarises our work on policy- enabled inter-network routing for mobile networks and adapting information services to available networking resources in tactical networks. The work ... -
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 ... -
Analysis of samples of high explosives extracted from explosive remnants of war
(2022-10-10)Millions of tonnes of dumped ammunition and explosive remnants of war remain in nature both on land and at sea. It is well known that the ordnance could represent a definite explosive risk if disturbed, and that some of ... -
A risk-increasing safety strategy? Evaluating the Traditional Risk-mitigating Strategy in Dealing with Dumped Ammunition and Explosive Remnants of War
(2022-10-16)In Norway, hundreds of thousands of tonnes of explosive remnants of war remain in nature. It has always been recognized that the ordnance could represent a certain explosive risk if disturbed, and that some of the constituents ... -
