One on the auroral probe POLRAD the radio spectro polarimeter to measure electromagnetic auroral kilometric radiation.

It doesn't emit in the electromagnetic spectrum. It doesn't reflect.

However, the ATSR instrument on board ERS 2 operated in the visible portion of the electromagnetic spectrum.

However, the ATSR instrument on board ERS 2 operates in the visible portion of the EM.

Hyperspectral imaging these systems acquire data over a range of wavelengths in the visible, short and long wave infrared (thermal) regions of the electromagnetic spectrum.

And light is part of the electromagnetic spectrum.

Could make some sort of landmark points along a spectrum of improbability, which might look like the electromagnetic spectrum we just looked at.

. A third instrument on board ERS 1 was the along track scanning radiometer (ATSR) that operated in three bands in the thermal region of the electromagnetic spectrum.

35. Improvements over the existing systems include higher spatial and spectral resolutions in both the visible and infrared portions of the electromagnetic spectrum, more frequent imaging, air mass analysis and more timely data dissemination.

(g) In the COMPAS project (Russian Federation) a satellite to investigate electromagnetic disturbances and the ionospheric plasma construction of the wave spectrometer operating in the frequency range of 0.1 15 MHz.

That allowed frequency re use in much the same way as a cellular phone network re used the spectrum.

The impact, observed in regions of the electromagnetic spectrum ranging from the ultraviolet to long radio wavelengths, produced fireballs that left major visible marks on the planet it revealed a clearcut need for an inventory of comets and asteroids that may someday collide with Earth.

The Workshop participants considered the ultraviolet domain to range from 100 to 350 nanometres (nm) in the electromagnetic spectrum.

51. It was noted that basic space science was increasingly coming into conflict with other, often commercially oriented space activities, such as in the use of the electromagnetic frequency spectrum.

MRI is using magnetic fields and radio frequencies to scan the brain, or any part of the body.

The Workshop noted that remote sensing satellites were used to observe, map and monitor features and phenomena on the Earth apos s surface in the optical, infrared and microwave regions of the electromagnetic spectrum.

Spek Spectrum Analyser

Or if we look in other parts of the electromagnetic spectrum, we see that there's a lot of gas in this cluster, as well.

And finally, about 100 years ago, the harnessing of electromagnetic spectrum to send sound and images through the air radio and television.

Realtime audio processor based on frequency spectral manipulation

So let's look at this in the context of the entire electromagnetic spectrum, where we have gamma rays.

The airwaves are used for a variety of communications, including government use and public access like radio. The range of usable territory the spectrum is administered by governments as though it were real estate, and is broken up according to wavelength, with an amount apportioned for cell phones, other bits for military pilots, and so on.

They reaffirmed that the radio electronic frequencies spectrum must be secured in favour of public interest and in accordance with the principle of legality.

It doesn't interact with the electromagnetic spectrum, which is what we use to detect things.

The Subcommittee noted that the use of spacecraft for making astronomical observations from above the atmosphere had greatly advanced knowledge of the universe by allowing observations in all regions of the electromagnetic spectrum.

(a) Forecasting, detecting and monitoring dangerous occurrences in the atmosphere and at sea (hurricanes, storms, typhoons, ice formations, etc.) with the aid of data supplied by satellites of the Meteor 3M and Elektro L types and received in different parts of the optical and radio (super high frequency) ranges of the electromagnetic wave spectrum

The ITU Plenipotentiary Conference in 1998 will consider the results of the review of the ITU spectrum orbit resource allocation procedure.

By invisible, I mean it doesn't absorb in the electromagnetic spectrum.

In general, the multispectral and radar instruments exploited different regions of the electromagnetic spectrum, and could often yield complementary information useful for tackling a variety of national development problems.

The review of the spectrum orbit resources allocation procedure is also under way with a view to increasing efficiency and equity in spectrum orbit utilization.
