Autonomous, Cooperative UAV Operations Using COTS Consumer Drones and Custom Ground Control Station
(2018)
The benefits of using UA Vs for inexpensive aerial surveillance and survey have been widely accepted, and UAVs are routinely assisting humans performing ISR operations. While large countries and well-funded military ...
Identification of mixed substances using a random forest regressor to classify THz absorbance spectra
(2018)
We report on the development and application of a random forest regressor that not only identifies but also estimates the relative concentrations of substances (one explosive and two simulants), both in one-substance and ...
Frequency agility radar with overlapping pulses and sparse reconstruction
(2018)
The use of frequency agility has a proven track record in radar systems. Altering the radar carrier frequency over shorter intervals improves the detection capabilities for slowly fluctuating targets and increases jamming ...
The Effects of a UAV on a Terrestrial MANET
(2018)
Technological advances on Unmanned Aerial Vehicles (UAVs) and autonomous control could make UAVs useful
for communication purposes, extending the range and increasing the performance of Mobile Ad-Hoc Networks (MANETs).
However, ...
Characterization of Variable Density 3D Printed Materials for Broadband GRIN Lenses
(2017)
In this work we design, simulate, manufacture and measure blocks made of variable density plastic. The density is controlled through varying the size of small cubes at the intersections of a fine grid. This structure is ...
Tiered Modelling - A Solution to Hyper-Coherent Morphological Models?
(2017)
Morphological models that comprise few constraints between parameter values are
considered hyper-coherent. A high degree of coherence in a model can be a problem if it results in
a large and unwieldy solution space. This ...
DVB-T Passive Radar Dual Polarization Measurements in the Presence of Strong Direct Signal Interference
(2017)
A dual-polarization passive bistatic radar is used to evaluate the potential benefit of cross-polarized measurements for the suppression of strong direct signal interference in the DVB-T band. The linear array antenna ...
Predicting Basic Military Performance for Conscripts in theNorwegian Armed Forces
(2017)
The Norwegian Armed Forces have made major changes to the enlistment and selection system for conscripts in recent years. In this article, the predictive validity of various selection criteria for military performance is ...
Results of a Ka Band Campaign for the Characterisation of Propagation Conditions for SatCom Systems at High Latitudes
(2017)
Satellite services in the High North are utilized extensively for both communication purposes and for earth and climate observations. This paper presents results of two year measurements at 20 GHz and co-sited meteorological ...
