Sentences with phrase «radio wave detector»

Not exact matches

Like the tuner on a radio, different detectors (bottom row) pick up different frequencies of gravitational waves.

But just as scientists use radio and gamma - ray telescopes to probe different frequencies of light, physicists are building detectors sensitive to a range of gravity wave frequencies.

Radar satellites come equipped with an antenna that sends radio waves to Earth; after hitting the planet's surface, the signal is reflected and scattered back toward a detector that generates an image without the need for visible light.

But in the late 1980s, new detectors opened their eyes to these ultrashort radio waves.

It acted like a funnel for radio waves, collecting them into its wide end and guiding them down into a detector.

Now, analyses of data gathered in 2006 by two satellites — one carrying a down - gazing camera and the other a gamma ray detector — as well as a ground - based lightning detector in North Carolina, reveal that these flashes start out, as does most lightning, as a small channel of charged particles within the storm cloud (golden zigzag line, left; lightning - generated radio waves are depicted as concentric rings).

But they still took great pains to rule out alternative explanations, scrutinizing a variety of detector data and the output of numerous on - site instruments that measure seismic activity, radio interference and many other possible sources of «noise» that could conceivably mimic a gravitational - wave signal, team members said.

Similar to how optical telescopes, X-ray telescopes and radio telescopes all look at different bands of the electromagnetic spectrum and teach us different things about the cosmos, the detection of gravitational waves at different frequency bands also requires different detectors.

After the Fuzzbuster I's debut, radar detectors evolved with each advancement in law - enforcement technology and eventually were able to detect radio waves for X -, K -, and Ka - bands.
