Origin and Nature of Electromagnetic Interference in X-band Weather Radars

摘要

Weather radars are experiencing an increasing amount of strong interferences caused by artificial radio sources, such as telecommunications systems, with a negative impact on radar quantitative measurements. In most European countries, operational weather radars operate at the C-band, in the 5.6 GHz frequency band, which is shared with Radio Local Area Networks (RLAN) and Wireless Local Area Networks. The impact of these telecommunications systems in weather radar measurements has been already discussed in literature.
