| Zusammenfassung |
| Radio science activities covered by URSI (International Radio Science Union) are briefly
reviewed. They encompass the knowledge and study of all aspects of electromagnetic fields
and waves in a wide frequency range running from micro pulsation frequencies (i.e. from
~1 mHz) to Terahertz. The topics include: electromagnetic measurements and
standards, electromagnetic theory and applications, radio-communication systems and
signal processing, electronics and Photonics, electromagnetic environment and
interference, wave propagation and remote sensing, ionospheric radio and propagation,
waves in plasmas, radio astronomy, and electromagnetics in biology and medicine.
The main radio science activities conducted by the URSI national Committees of
South Africa, Egypt and Nigeria, and by African radio scientists groups gathered in
GIRGEA (Groupe International de Recherche en Géophysique Europe Afrique) are
reviewed. The emphasis is put on the activities developed in the context of the IHY
programme and of the SCINDA network for forecasting ionospheric irregularities that
adversely impact communication and navigation systems in the low latitude regions. |
