Polarimetric scattering calculation based on Maxwells equations for very high resolution SAR
(2004)A method for raw signal generation for extended SAR (Synthetic Aperture Radar) scenes with very high resolution is described. Such a simulator shall handle resolution better than 30 cm, squinted geometry, elliptical orbit ... -
Polarization dependence in CHESS fiber optic strain monitoring system based on fiber Bragg gratings
(2002)This report describes the polarization dependence in the hull monitoring system CHESS, developed in FFI project 79301 CHESS II. The report describes the polarization behaviour of some main components in the system, ... -
Police forces with military status in international peace operations - preliminary findings
(2002)Recent peace operations are characterised by a gap between a large number of heavily-armed military forces and the international civilian police – often few in number and if at all equipped with light weapons (the so-called ... -
Policy og praksis for gjenkjøp - en komparativ studie av sju nasjoner
(2006)The Norwegian offset guidelines are up for revision, and this study has been part of a process of establishing a new Norwegian offset policy and practice. The purpose of this report has been to conduct a comparative study ... -
Polycarbonate in transparent armour – mechanical properties, ballistic performance and ageing behaviour
(2023-08-14)Polycarbonate is an engineering plastic that is frequently used as a component in, or as a stand-alone, transparent armour for many military applications. One important application of polycarbonate is in transparent armour ... -
Possible effects of the 2003 invasion of Iraq on the nuclear programs in Iran, North Korea and Libya
(2014-01-09)In 2003 the nuclear programs in North Korea, Iran and Libya all took a radical new turn; North Korea left the Treaty on the Non-Proliferation of Nuclear Weapons; Iran halted parts of its nuclear program and signed the ... -
The potential impact of 1-8 kHz active sonar on stocks of juvenile fish during sonar exercises
(2005)The mortality threshold for juvenile herring exposed to sonar signals is 180-190 dB (re 1μPa), and for other species even higher. This report analyses the potential impact of sonar transmissions on recruitment to important ... -
Praktisering av verneplikten i Norge 1814-2000
(2000)This paper discusses the principle of general conscription and implementation of that principle in Norway from 1814 to the end of the 20th century. The principle of general conscription contains within itself a contradiction ... -
Predicting scalar coupling constants via machine learning
(2021-12-22)Over the preceding decade, machine learning techniques have been successfully applied in several fields of research, including the prediction of chemical properties of atoms and molecules. Whereas conventional quantum ... -
Prediction of concrete penetration using Forrestals formula
(2000)The various existing empirical formulas for predicting penetration into concrete targets are seen to give different results. Explaining the difference is difficult since most of the original empirical data behind the ... -
Preliminary assessment of the vertical release of liquefied chlorine inside a depression
(2009)Toxic industrial chemicals (TICs) are used in most places and can pose a threat due to accidents, terror, or sabotage. Many of the most common TICs are gasses at ambient atmosphere, such as chlorine, ammonia, and sulfur ... -
Preliminary numerical simulation of the dispersion of chlorine vapour in a mock urban environment for the Jack Rabbit II field trials
(2016-02-02)The release and dispersion of toxic industrial chemicals as a result of accidents, terrorism, or sabotage represent a possible hazard for life and health. Such chemicals are often transported and stored as condensed ... -
Preparation of biological contaminated samples for chemical analysis
(2009)FFI has established laboratory facilities in order to receive and analyze samples containing a mixture of chemical, biological and radiological (CBR) agents, so-called “mixed samples”. Detailed procedures are needed to ... -
Presisjonsstyrte våpen i de senere års konflikter
(2004)This report gives an overview and a discussion of the development and utilisation of long-range precision guided munitions in recent military operations – starting with Desert Storm in 1991. The open literature has been ... -
Prestasjonsbasert logistikk (PBL) - muligheter og utfordringer
(2011-11-01)Prestasjonsbasert logistikk, eller Performance-Based Logistics (PBL), er et relativt nytt konsept for understøttelse av militære systemer. En grunntanke i PBL er endringen fra den tradisjonelle transaksjonsbaserte formen ... -
Prinsipper for en bærekraftig forsvarsøkonomi
(2015-10-08)I denne rapporten diskuteres prinsipper for en bærekraftig forsvarsøkonomi. Prinsippene er allmenne og kan vektes ulikt avhengig av hvilken forsvarsstruktur de anvendes på. I rapporten defineres bærekraftig forsvarsøkonomi ... -
Prinsipper for norsk avskrekking – en operasjonsanalytisk tilnærming
(2019-05-08)Forsvarets oppgave nummer 1 er å «Sikre troverdig avskrekking med basis i NATOs kollektive forsvar». I denne rapporten diskuterer vi hva som kan ligge i «troverdig avskrekking» ved å bruke operasjonsanalyse som verktøy. ... -
