Incoherent scatter
Incoherent scattering is a type of scattering phenomenon in physics, which may involve various particles, such as neutrons or photons.One application is a ground-based technique for studying the Earth's ionosphere. A radar beam scattering off electrons in the ionospheric plasma creates an...

Radar
Radar is an object-detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish or antenna transmits pulses of radio...

History
In 1973 the EISCAT proposal - which was originally planned for France, Germany and the three Nordic countries seemed moribund. Then a Welshman, Granville BeynonGranville Beynon
Granville Beynon was a Welsh physicist who took active part in preparation and performance of the International Geophysical Year 1957/8 which is known as a breakthrough in international cooperation in geophysics. Beynon became thereafter one of the leading personalities in international scientific...
became involved and by 1975 the agreement was signed, with the UK as a member. The proposal for UK membership had originally been turned down by the appropriate SRC committee. Beynon, however, persuaded the Board to reverse the decision of the committee and as a result of his efforts hundreds of European scientists have had the opportunity to use the world's most advanced ionospheric radar.
