Description
Summary:A new type of imaging riometer system based on a Mills Cross antenna array is currently under construction by the Ionosphere and Radio Propagation Group, Depart-ment of Communication Systems, Lancaster in collab-oration with the Max-Planck-Institut für Aeronomie, Germany. The system will have an unprecedented spa-tial resolution in a viewing area of 300 300km. It is located at Ramfjordmoen, near Tromsø, Norway. The riometer (relative ionospheric opacity meter) deter-mines the radio-wave absorption in the ionosphere by measuring the received cosmic-noise power. The ex-pected variation of background noise over a sidereal day is usually referred to as the quiet-day curve (QDC). The ionospheric opacity is deduced from the difference be-
