17 hours ago · Synthetic aperture radar (SAR) allows satellites to bounce radar signals off the ground and interpret the echo – and it can even peer through clouds. C. Clouds cover around two-thirds of the ...
1 day ago · Radome. The radome is a spherical enclosure atop the tower or roof-mounted radar components. This shell must be manufactured to be larger than the antenna to ensure the antenna can move freely inside the radome. This critical component protects every element within its environment and is transparent to the radar beam.
5 days ago · Radiofrequency weapons either couple energy into a target’s intended electromagnetic apertures, known as “front-door” coupling, or through unintended ones, called “back-door” coupling ...
2 days ago · Two of the satellite's instruments will flash light at the clouds to probe their depths. The Lidar instrument will use a laser pulse to measure both clouds and aerosols, which are tiny particles ...
2 days ago · The outgoing longwave radiation (OLR) emitted by the Earth’s surface and atmosphere is a critical component of the planet’s energy budget and plays a crucial role in the climate system. Understanding the vertical distribution of OLR is essential for developing accurate climate models and improving our understanding of atmospheric processes.
5 days ago · The more energy is released, the more damage is likely to occur on the ground due to the environmental effects triggered by the impact. Such effects can be shock waves, heat radiation, the formation of craters with associated earthquakes, and tsunamis if bodies of water are hit.
17 hours ago · Quantum mechanics. Quantum entanglement is the phenomenon of a group of particles being generated, interacting, or sharing spatial proximity in such a way that the quantum state of each particle of the group cannot be described independently of the state of the others, including when the particles are separated by a large distance.
