Multiband Passive Bistatic Radar Coherent Range and Doppler-Walk Compensation
(2015)
The work simulates the performance of a coherent Passive Bistatic Radar multiband processing algorithm. The aim of the work is to present improved range resolution by coherently combine non-adjacent DVB-T channels, while ...
Underwater Acoustic Network Simulation With Lookup Tables From Physical-Layer Replay
(2015)
An underwater acoustic network simulation methodology is presented that is based on lookup tables (LUTs) with physical-layer error ratios. These LUTs are prepared with a validated replay channel simulator, which is here ...
The use of synthetic aperture sonar to survey seafloor massive sulfide deposits
(2015)
With the advent of advanced deep sea mining technology, seafloor mining is poised to begin on a
global scale. For the success of any mining operation, it is crucial that both the operators and
regulatory bodies possess ...
Dose response severity functions for acoustic disturbance in cetaceans using recurrent event survival analysis
(2015)
Behavioral response studies (BRSs) aim to enhance our understanding of the behavior changes made by animals in response to specific exposure levels of different stimuli, often presented in an increasing dosage. Here, we ...
Identification and quantification of lichenysin – a possible source of food poisoning
(2015)
Lichenysin produced by 53 different Bacillus licheniformis strains has been structurally examined with a qualitative liquid chromatography-tandem mass spectrometry (LC-MS/MS) method using quadrupole-time-of-flight mass ...
Completeness and Accuracy of a Wide-Area Maritime Situational Picture based on Automatic Ship Reporting Systems
(2015)
Automatic ship reporting systems (AIS – Automatic identification System, LRIT – Long Range Identification and Tracking, VMS – Vessel Monitoring System) today allow global tracking of ships. One way to display the results ...
Toward federated mission networking in the tactical domain
(2015)
NATO is currently working on the Federated Mission Networking (FMN) concept, which will become the foundation for establishing mission networks in the future. The realization of the FMN concept is described in the NATO FMN ...
Modeling of a back-illuminated HgCdTe MWIR avalanche photodiode with alloy gradients
(2015)
We present results from 2D Monte Carlo simulations of a mid-wave infrared (MWIR) back-illuminated planar n-on-p HgCdTe electron-initiated avalanche photodiode (e- APD). The main objective of this work has been to study the ...
Spin scan tomographic imager
(2015)
A novel imaging device based on tomographic reconstruction is presented. The imager is based on rotating an image of the scene onto a linear detector array, and then reconstructing a 2-dimensional image from the detector ...
Assessing Islamic State’s Commitment to Attacking the West
(2015)
How much of a terrorist threat does the Islamic State (IS) pose to Western countries? This article looks at what IS has said and done with regard to attacks in the West. We examine IS statements and take stock of IS-related ...
