Estimation of orientation of an aircraft using position data only
(2022-09-26)
This report introduces a method for estimation of an aircraft’s orientation on the basis of measurements
of its position only. Typical sources for the position data is global navigation satellite systems or radar
measurements. ...
Modeling FMCW Radar for Subsurface Analysis
(2022-04-05)
Determining subsurface properties through ground penetrating radar sounding can be challenging, especially in planetary exploration, where little is known about the terrain and additional observations are limited. Analysis ...
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 ...
Hvordan kan Forsvaret raskere nyttiggjøre seg ny teknologi? – om behovene for grunnleggende endringer i måten vi utvikler og investerer i teknologi og forsvarsmateriell
(2022-10-20)
Forsvaret har en ambisjon om å raskere nyttiggjøre seg framvoksende og moden teknologi. Det utfordrer dagens innretning av investeringsprosessen. Ambisjonen berører også politikkområder som langtidsplanlegging, ...
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 ...
Modeling the effect of random roughness on synthetic aperture sonar image statistics
(2022-09-02)
A model has been developed to predict the effect of random seafloor roughness on synthetic aperture sonar (SAS) image statistics, based on the composite roughness approximation–a physical scattering model. The continuous ...
Modelled sonar and target depth distributions for active sonar operations in realistic environments
(2022-09-08)
Target detection performance of mid-frequency active sonars depends heavily on both sonar and target depth. For a given target depth, a sonar performance model may help predict a sonar depth that maximizes the detection ...
Fra teknologi til strategi og operasjoner – teknologiutviklingens påvirkning på militære styrker og bruken av militærmakt
(2022-08-22)
Denne rapporten inngår i prosjektet Globale trender og militære operasjoner III, og behandler sammenhengen mellom teknologi og den operative bruken av militære styrker. Det vil si mellom teknologiutviklingen og konseptene ...
Emerging technology trends for defence and security
(2020-04-07)
This review is the first of a series of studies from a new research programme at the Norwegian
Defence Research Establishment (FFI) tasked with identifying emerging technology trends and
analysing their potential impact ...
Velgeren som tilskuer: "Valgbarisme" i amerikanske presidentvalg
(2021)
Hensyn til valgbarhet har i kraft av det amerikanske politiske systemets virkemåte bestandig vært et moment i presidentvalg. I nominasjonskampen i 2020 har dette hensynet imidlertid vært viktigere for et flertall av velgere ...
