Rotor's nearly $1 million Sprayhawk helicopter is a Robinson R44, but the four seats have been replaced with flight computers and communications systems allowing it be operated remotely. It has five cameras as well as laser-sensing technology and a radar altimeter that ...
Vision-Based Support for the Detection and Recognition of Drones with Small Radar Cross Sections Drones are increasingly vital in numerous fields, such as commerce, delivery services, and military operations. Therefore, it is essential to develop advan... SE Abdelsamad,MA Abdelteef,OY Elsheikh,....
coal fire detection is a key technology. In this paper, thermal infrared remote sensing from unmanned aerial vehicle combined with a surface survey is used to identify the range of coal fires in the Huojitu coal mine in Shenmu city. The scopes and locations of the fire zones are preliminaril...
Along the volatile border, a shell fired from inside Syria landed on a home in the Turkish village of Akcakale, killing a woman, her three daughters and another woman, and wounding at least 10 others, according to Turkish media. Turkey's NTV television said Turkish radar pinpointed the pos...
Detecting Coal Fires in China Using Differential Interferometric Synthetic Aperture Radar (InSAR). Proceedings of the FRINGE 2003 Workshop (ESA SP-550), Frascati, Italy, 1–5 December 2003; p. 501. [23] Prakash, A.; Fielding, E.J.; Gens, R.; van Genderen, J.L.; Evans, D.L. ...
Lingering smoke in the Amazon caused concern Tuesday among Brazilians who say that respiratory problems—particularly among children and the elderly—have increased as fires in the region rage.
where W{·} is the wrapping operator, which indicates that the differential interferometric phase is modulo-2π, and λ is the wavelength of the radar signal. 𝑑𝑡𝐴𝑥,𝑦−𝑑𝑡𝐵𝑥,𝑦dx,ytA−dx,ytB is the displacement that has occurred between the two radar acquisitions ...
Furthermore, the fire incidences are segregated on basis of weekdays and hours to arrive at the maximum frequency by circular statistics represented in radar charts. Pearson’s correlation is evaluated for the hourly fire frequencies using Equation (12) and the sensitivity analysis is performed by ...
