Determination of detonation velocity and plate dent properties of PBXV-11 with 30 WT.% aluminium
(2008)Studied composition PBXW-11with 30wt.% aluminium class 7 powder is a Norwegian produced explosive equal to the American PBXIH-18 composition. By slightly modification of the aluminium content the studied composition will ... -
Determination of detonation velocity and pressure for MCX-6100
(2015-12-02)Independent of the application of an explosive composition there are certain properties that are important to know. Performance depends on properties as detonation velocity and detonation pressure. Sensitivity of munitions ... -
Detonation transfer : summary report, FFI project 803.03
(2003)In connection with the upgrade of AMRISK, a program for risk analysis of ammunition storages, the process of detonation transfer have been studied. Based on earlier work a model for sympathetic detonation is developed ... -
DETOUR trials: The mission and its results
(2017)In this paper DMPAR Evaluation Trials for Operationally Upgraded Radar (DETOUR) and their results for a selected scenario are described. The DETOUR trials were conducted by the SET-195 research task group (RTG) under an ... -
Development and Calibration of a Low-Cost Radar Testbed Based on the Universal Software Radio Peripheral
(2019-12-01)For a cognitive radar algorithm to be useful, it must run on radar hardware that is flexible. Typically, this has been viewed as requiring a software-defined radio. With the emergence of cheap, digital transceiver systems, ... -
Development of a chemical, atomic and toxic compound surveillance system - CATSS
(2004)A demonstrator of an automatic surveillance system for chemical, radiological and toxic compounds, called CATSS, has been developed at FFI. The system contains several commercially available detectors integrated into CATSS. ... -
Development of LES inflow conditions for turbulent boundary layers
(2013-10-31)Computational Fluid Dynamics (CFD) is currently the only known physically based method to model dispersion and transport of aerosols and gases in complex urban environments. One of the main challenges with CFD simulations ... -
Development of material models for semi-brittle materials like tungsten carbide
(2010)Tungsten carbide is a very special material that exhibits both brittle and ductile properties. While purely brittle and ductile materials in general are well understood, a theory for describing the properties of a hybrid ... -
Development of neuropathology following soman poisoning and medical countermeasures
(2018)Nerve agent-induced seizures can cause varying degrees of neuropathology depending on level of poisoning and duration of seizing. The intention of this review was to validate a novel approach for establishing effective ... -
Diffuse kilder til PCB og effektstudier i torsk og blåskjell ved Haakonsvern orlogsstasjon
(2003)Studies of diffuse sources of PCB in addition to studies of toxicological and physiological effects in cod and blue mussel has been carried out at Haakonsvern Naval Base in connection with a clean up of PCB contaminated ... -
Digital interferometribasert retningsbestemmelse av radarpulser
(2004)This report concerns experiments performed during the course of project KREST with regard to radar signal direction finding. The study comprises implementation of commercial off-the-shelf (COTS) components in a ... -
Digital multistatisk radar - overordnet maskinvarebeskrivelse
(2002)This report gives a high level description of a radar demonstrator made for demonstrating bistatic radar. The demonstrator consists of one transmitter and one receiver unit. An overview of the hardware used in the ... -
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 ... -
Digitalt kalibrerte radarmålinger med usynkronisert sender og mottaker
(2001)The report describes a signal processing algorithm used on radar data collected from a unsynchronized radar system. The algorithm makes corrections for the missing synchronization between transmitter and receiver, and has ... -
Direct signal cancellation in passive bistatic DVB-T based radar
(2014-08-19)Passive radars receive target reflections from transmitters of opportunity. They do not emit any radiation, which makes them harder to find. A challenge with the passive radar is to suppress the strong direct signal ... -
Direction finding experiment in North Scandinavia
(2003)High-frequency (HF) radio wave propagation at high latitudes is greatly affected by geomagnetic and ionospheric conditions, and both civilian and military users need reliable forecasts of the propagation environment. In ... -
Discrete Fourier Transform with Neural Networks
(2021-12-10)The discrete Fourier transform is an important computational tool to retrieve the frequency distribution of a sampled signal. Recent years have also witnessed considerable research activity in neural networks as a mean to ... -
Discriminating between camouflaged targets by their time of detection by ahuman based observer assessment method
(2015)Detection of a camouflaged object in natural sceneries requires the target to be distinguishable from its local background. The development of any new camouflage pattern therefore has to rely on a well-founded test methodology ...
