Wideband Interferometry in Synthetic Aperture Sonar
(2013)Synthetic aperture sonar (SAS) interferometry can provide very high resolution images and topographic maps of the seafloor over large swaths. Processing of interferometric data to retrieve reliable depth estimates of the ... -
Wideband Propagation Characteristics at 312 MHz in Eastern Norway and Impact on Waveform Requirements
(2015)A wideband Pseudo-Noise channel sounder built by CRC in Canada has been used to measure the wideband channel characteristics in three different types of terrain in Eastern Norway. The channel characteristics at 312 MHz are ... -
Wideband Synthetic Aperture Sonar Back Projection with Maximization of Wave Number Domain Support
(2017)Wideband and widebeam synthetic aperture sonar (SAS) can provide information on the frequency- and aspect-dependent scattering in a scene. We suggest an approach to predict the quality of the sensor data over the available ... -
WiMAX - teknologi, funksjonelle egenskaper og sikkerhet
(2010)I dag er det en rivende utvikling innen infrastrukturer for elektronisk kommunikasjon. Trenden er at sivile og militære kommunikasjonsinfrastrukturer smelter sammen, både i forhold til teknologibruk og anvendelse. Sivile ... -
WiMAX ytelsesmålinger i skogsterreng
(2008)Det er et behov for økende overføringskapasitet til brukere av trådløse kommunikasjonssystemer, også i Forsvarets taktiske avdelinger. Dette behovet kan trolig til en viss grad dekkes ved bruk av nye sivile mobile ... -
Wind Turbines and Electromagnetic Systems (WTES) - software documentation
(2007)This report contains a description of the software developed by the FFI-project 1013 “Effekt av vindkraftutbygging på radiosamband og radar (VINDKRAFT)” (The effect of windmill development on telecommunication and ... -
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 ... -
Windfarm Impact on Electromagnetic Systems (WIMP) - software documentation
(2007)This report is a description and user manual for the software developed at Teleplan according to the co-operation agreement between Teleplan and the FFI-project 1013 “The effect of windmill development on telecommunication ... -
Wireless power transfer in the presence of metallic plates: Experimental results
(2013)We demonstrate efficient wireless power transfer between two high Q resonators, especially in a complex electromagnetic environment. In the close proximity of metallic plates, the transfer efficiency stays roughly the same ... -
Wireless Sensor Networks - Trådløse sensor nettverk
(2006)This report gives a brief overview of Wireless Sensor Networks and the status of this technology. WSN is a new and promising technology that shows a great potential for the armed forces. Only a limited effort in the NbF-Grid ... -
The WISDOM Radar: Unveiling the Subsurface Beneath the ExoMars Rover and Identifying the Best Locations for Drilling
(2017)The search for evidence of past or present life on Mars is the principal objective of the 2020 ESA-Roscosmos ExoMars Rover mission. If such evidence is to be found anywhere, it will most likely be in the subsurface, where ... -
Wound profiles in soap caused by penetration of high speed spheres
(2002)As a first attempt at identifying a tissue model for use in wound ballistic simulations a study of the wound profiles in soap during deceleration of spherical steel projectiles has been carried out. Experimental data were ... -
XML and Web Services Security
(2008)Denne rapporten gir en oversikt over sikkerhetsstandarder for XML og Web services. Rapporten omfatter blant annet XML Signature, XML Encryption, XML Key Management Specification (XKMS), WS-Security, WS-Trust, WS-SecureCo ... -
XML and Web services security standards
(2009)XML and Web services are widely used in current distributed systems. The security of the XML based communication, and the Web services themselves, is of great importance to the overall security of these systems. Furthermore, ... -
XML Based Certificate Management
(2008)The need for key management in SOA-based systems is addressed in this report. The report starts with a presentation of key management principles and a discussion of the problem posed by the PKI (Public Key Infrastructure) ... -

(2014-06-02)På oppdrag fra NAMMO Bakelittfabrikken AS har FFI undersøkt arbeidsmiljøet knyttet til noen spesielle arbeidsoppgaver på fabrikken. FFI fikk i oppdrag å undersøke om de ansatte kunne eksponeres for helseskadelige stoffer ... -
Ytelsen av standard HF-modemer på norske breddegrader
(2000)The high latitude HF channel has been measured and characterised in terms of Doppler spread, delay spread and signalto-noise ratio. The performance of data modems has been determined over a comprehensive range of simulated ... -
ZnGep2-based optical parametric oscillator for µm generation
(2004)Operation of a ZnGeP2-based optical parametric oscillator (OPO) for generation of 8-11 μm radiation is studied. The primary source used to pump the OPO is a KTP-based OPO pumped by a Nd:YAG laser, giving up to 2 mJ pump ... -
Øke bemanningen i Forsvaret i dramatisk nedgangskonjunktur? En samfunnsøkonomisk vurdering
(2021)Koronapandemien har resultert i kraftige fall i etterspørsel, produksjon og sysselsetting i Norge og internasjonalt. Arbeidsledigheten i Norge er nå unormalt høy. Arbeidsøkonomisk litteratur har påvist at det er kostbart ... -
