International X-Band Weather Radar Workshop, 14-16 November, 2011, Delft, Netherlands

The installation of compact X-band weather radars becomes increasingly popular as such radars deliver rainfall rate information in a very high spatial and temporal detail which are required for applications such as the monitoring of rainfall in urban areas or water catchment hydrology.

However, X-band weather radar observations pose challenges e.g. in terms of the prevailing scattering mechanisms and the significant attenuation by rain which makes the seamless application of methods and algorithms developed for S- and C-band disputable.

The objective of this workshop is to serve as a platform for experts on X-band weather radar in order to discuss the latest developments in the field. A plenary discussion is scheduled to evaluate the state-of-the-art for rainfall measurements with X-band weather radar and to discuss the possibility of writing a reference book on this topic.

Под Иркутском взорвали крупнейшую РЛС

Строили долго, взорвали быстро. В Усольском районе, недалеко от деревни Мишелёвка, ликвидировали радиолокационную станцию "Дарьял-У" системы предупреждения о ракетном нападении.

Проезда нет. За два часа до взрыва все подъезды к месту перекрыты. Солдаты находятся в веселом настроении. Как-никак на природе, это не по плацу ходить. А вот у сотрудников дорожной полиции нервного общения больше.

До деревни Мишелевка от военного объекта пару километров по прямой. О взрыве командование войсковой части предупредило заранее. В специальных листовках объяснили, что все под контролем. Однако слухи по поселку гуляли разные.

- Говорили, что много взрывчатки заложили, что будет очень сильный взрыв, - говорит жительница пос. Мишелевка Татьяна Касинцева.

Acoustic mirror at Denge

Acoustic mirror at Denge

Prior to World War II and the invention of radar, acoustic mirrors were built as early warning devices around the coasts of Great Britain, with the aim of detecting airborne invasions. The most famous of these devices still stand at Denge on the Dungeness peninsula and at Hythe in Kent. Other examples exist in other parts of Britain (including Sunderland, Redcar, Boulby, Kilnsea) and Selsey Bill, and Bahar ic-Caghaq in Malta. The Maltese sound mirror is known locally as "the ear" (il-Widna) and appears to be the only sound mirror built outside Great Britain.
