Autonomous Optical Survey Based on Unsupervised Segmentation of Acoustic Backscatter
(2018)
The application of acoustics to study the seabed have for decades provided industry and science with valuable information, and is still excels in terms of spatial coverage and detail. An acoustic response from the seabed ...
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, ...
Predicting Near-Time Satellite Signal Attenuation at Ka-band Using Tropospheric Weather.
(2018-12-10)
There are satellite communication applications where it is desirable to predict near time (e.g. 2 to 12 h) propagation losses at Ka-band due to hydrometeor precipitation. We present results from a project investigating the ...
Guidelines for using animal models in blast injury research
(2018)
Blast injury is a very complex phenomenon and frequently results in multiple injuries. One method to investigate the consequences of blast injuries is with the use of living systems (animal models). The use of animals ...
Full characterization of spatial coregistration errors and spatial resolution in spectral imagers
(2018)
For multi- and hyperspectral imagers, the integrity of the spectral information depends critically on the spatial coregistration between bands. There is at present no commonly accepted way to fully specify coregistration ...
