Matched-field localization of explosive sources in the Barents Sea using a horizontal array
(2002)
Matched-field processing (MFP) techniques are used to estimate the range and depth of underwater explosive sources.
Data from an experiment conducted by FFI in the Barents Sea 1999 is used. The experiment was conducted ...
The joint NO and UK demonstration of integrated MMHS, PKI and Directory Systems at JWID 2003
(2002)
This report describes the joint NO and UK interoperability testing of integrated MMHS, PKI and Directory Systems conducted at JWID 2003. Joint Warrior Interoperability Programme (JWID) is a yearly event with the main site ...
Vegetation attenuation of microwaves - measurements and model evaluation
(2002)
The aim of this report is to analyse measurements of vegetation attenuation at 18GHz and 38GHz. The
transmitter and the receiver are both located in the forest in such a way that the main part of the radio wave
propagate ...
Multifunctional numerical tool for penetration analysis
(2002)
An advanced analytical/numerical tool for calculating penetration of rigid projectiles into various materials is described.
The program is based on cavity expansion theory (CET) and is a further development of an earlier ...
Range localication of 10-100 km shots by means of an endfire array and a waveguide invariant
(2002)
During a shallow-water acoustic experiment, signals from small explosions were recorded on an endfire horizontal
array. The experiment took place in open waters with relatively slow changes of the water depth with range. ...
Penetration into concrete - analysis of small scale experiments with 12 mm projectiles
(2002)
The analytical approach for predicting penetration of rigid projectiles into concrete targets indicates that the scaled
penetration depth is a function of only two non-dimensional parameters. This report analyses experiments ...
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.
Brukermanual til datastøtteverktøy - tiltak for fysisk sikring av Forsvarets objekter
(2002)
Measures for physical security of military objects have been proposed in an earlier work (FFI/RAPPORT-2000/06432
“Method for evaluating the security of military installations”). This report is the user manual for a computer ...
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 ...
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 ...
