Authors Lindsey Wiley, Joshua Follansbee, Patrick Leslie, Orges Furxhi, Rich Pimpinella, David Brady, Ronald Driggers


The article examines target detection using drones in various reflective bands, with a particular focus on the short-wave infrared (SWIR) band. The study highlights the advantages of SWIR, including increased atmospheric transmission and object-sky contrast, making it suitable for low-illumination conditions. The Zephir 2.5 camera is used for imaging in the SWIR band. The research emphasizes the significance of pixel pitch and contrast for imaging performance across all bands.
