Inverse modeling of penetration into 12.7 cartridges
(2002)In this article a study of the forces caused by penetration of steel penetrators into cartridges of brass has been carried out. Experimental data was compared with simulations using the Nike-2D code and with solutions ... -
A model of internal ballistics properties in gun tubes
(2002)In this report a study of the pressure generated by burning of gunpowder in gun barrels has been carried out. Calculations using the model were compared with experimental results and with results from the standard ... -
Radardekningssimulator - fysikk
(2002)Project 726 has developed a multistatic radar coverage prediction tool for frequencies above 100MHz. Various physical effects such as reflection, diffraction, refraction, attenuation due to precipitation and atmospheric ... -
Bottom reverberation predictions with the acoustic model Lybin - a comparison between three bottom backscattering algorithms
(2002)Comparing the three bottom backscattering algorithms we observe variations in the resulting bottom reverberation levels from 0 to more than 20 dB in some cases. Concentrating on the variations at shorter to medium ranges ... -
Rekonfigurerbar prosseseringsmodul - IOkort
(2002)This is a flexible multipurpose IOcard designed for fast prototyping, including the multipurpose programmable processing card that are designed. It contains digital IO and analogue IO. -
Rekonfigurerbar prosseseringsmodul - FPGAkort versjon2
(2002)This design is a multipurpose programmable processing card. It is based on three Field Programmable Arrays for Xilinx. This report describes the hardware and layout for usage of this card. -
Rekonfigurerbar prosseseringsmodul - FPGAkort versjon1
(2002)This design is a multipurpose programmable processing card. It is based on three Field Programmable Arrays from Xilinx. This report describes the hardware and layout for usage of this card. -
Interoperabilitet - kostnadsdriver og styrkemultiplikator
(2002)The main aim of this report is to analyse Interoperability (IO) of military forces and the consequences for Norway of more emphasise on IO, both nationally and in NATO. The first part of the report argues that IO is a ... -
Mulige russiske reaksjoner på ulike former for NATO-utvidelse
(2002)NATO is, for the second time, going to include new members from East-Central Europe. In view of the experiences from the first eastward expansion the possibility of a strong Russian reaction was seen as the main obstacle ... -
Digital multistatisk radar, sender og mottaker
(2002)This report describes the receiver and the transmitter designed for verifying a multistatitic radar concept. The digital part of the receiver and the transmitter are based on FPGAs. The report also describes the software ... -
Space-based AIS : theoretical considerations and system parameter optimization
(2006)The recently introduced Universal Automatic Identification System (AIS) is a ship-to-ship and ship-to-shore reporting system based on broadcasting of messages in the maritime VHF band. The AIS messages could also be ... -
Multistatisk CW radar - konsept
(2002)A technical concept study of digital multistatic radar has been executed in project 726. The concept is based on the use of a number of low cost lightweight transmitters and an advanced high-priced passive receiver unit. ... -
RF-maskinvare for digital bistatisk radar
(2002)This paper covers the RF-HW made as a technology demonstrator for a bistatic radar system. Both the transmitter and the receiver are described in detail. By designing and building the radar we gained insight in using and ... -
Er sivil infrastruktur sannsynlege mål for terrorgrupper i fredstid? : nokre førebelse konklusjonar om terrorisme som tryggingspolitisk utfordring i Norge
(2000)The report discusses terrorism as a security policy challenge in Norway. It gives a broad survey of recent trends in terrorism and briefly discusses the potential for weapons of mass destruction terrorism. The report also ... -
Beregning av deteksjonssannsynlighet for mono-, bi- og multistatiske radarsystemer
(2002)This report describes results from a mono-, bi- and multistatic radar cross-section simulator. Results presented show that a multistatic radar system has a significantly higher probability of detecting a low-signature ... -
Mono- og bistatisk radartverrsnittsberegnings-program
(2002)In this report we describe a simulator, which is capable of predicting mono-, bi- and multistatic Radar Cross Section (RCS) of Computer Aided Design (CAD)-generated objects. The model is based on physical optics (PO) and ... -
Nedbrytningsprodukter av nervegasser analysert med væskekromatograf tilkoblet atmospheric pressure ionization elektrospray massespektrometer (HPLC-API-ES-MS) - del II: Negativ ion modus
(2002)Hydrolysis products of nerve agents have been analysed by HPLC coupled to an API-ES-MS in SIM mode. Parameters for the instrument were optimised for MPA, EPA, EMPA, IPMPA and PMPA. The instrument's detection limits for ... -
