Spectral reflectance measurements of snow and snow covered objects: experimental studies compared with mathematical models
(2021-09-12)
In this study, we have investigated reflectance spectra of different snow types under various conditions. Snow reflectance is interesting from a camouflage point of view as snow covers large land areas in many parts of the ...
The First GAEN-Based COVID-19 Contact Tracing App in Norway Identifies 80% of Close Contacts in “Real Life” Scenarios
(2021-11-17)
The coronavirus disease 2019 (COVID-19) response in most countries has relied on testing, isolation, contact tracing, and quarantine (TITQ), which is labor- and time-consuming. Therefore, several countries worldwide launched ...
Spectral characteristics of moist birch leaves and synthetic materials: experimental studies and evaluation of models
(2021-11-09)
The optical depth of biomaterials and natural backgrounds varies with their environment and incoming light properties. Deciduous trees, for instance, have canopy thicknesses that vary significantly from one place to another. ...
In situ performance prediction of a coherent acoustic modem in a reverberant environment
(2021-07-28)
A channel sounding and communications experiment was performed in the Oslofjord, using eight bottom-mounted instrument units deployed in a network configuration. Five units were equipped with a software-defined 4–8-kHz ...
Multimodal change monitoring using multitemporal satellite images
(2021-09-12)
The main objective of this study is to monitor the land infrastructure growth over a period of time using multimodality of
remote sensing satellite images. In this project unsupervised change detection analysis using ITPCA ...
Optimization of active sonar parameters in a measured environment
(2021-09-13)
ABSTRACT
Sonar operation in coastal waters is challenging due to high false alarm rates and strongly varying sonar conditions. Optimal choices for sonar design and pulse characteristics depend strongly on target location ...
Detection of Point Scatterers in Medical Ultrasound
(2021-11-19)
We present an overview of the detection of point scatterers in ultrasound images and suggest strategies for evaluating and measuring the detection performance. We use synthetic aperture Field II simulations of a point ...
Leveraging network-centric strategic goals in capabilities
(2021-04-19)
The vision of network-centric operations is to increase operational capabilities through networked collaboration. NATO and its member nations state this vision in strategic documents at a very high level of abstraction. ...
Forsvarsanalysen 2022
(2022-03-15)
FFI-prosjektet «Strategiske forsvarsanalyser» ble opprettet 1. januar 2021. Forsvars-departementet (FD) er oppdragsgiver, og forsvarssjefen er sektorens hovedrepresentant. Prosjektets hovedprodukt er en årlig analyse som ...
LandX20 Experiment Report – experiment for future land warfare capabilities with focus on increased situational awareness and unmanned systems
(2022-03-21)
LandX20 was a collaborative experiment and demonstration where four research projects from the
Norwegian Defence Research Establishment (FFI) participated. The goal of the experiment was
two-fold. The first goal was to ...
