Medición de Señales WLAN/RLAN que Interfieren a los Radares Meteorológicos Argentinos

The aim of this work is to measure and characterize WLAN/RLAN wireless network signals which interfere with the radars of the argentinian National Meteorological Radar System (SINARAME) and degrade their performance. The standards that define these signals are studied and a measurement procedure is designed, which allows recording the interference sources in-situ and also determining their origin.The first step involves the analysis of weather radar records, where the effects of the interference on the generated products are observed to determine critical azimuthal directions on digital cartography, which are used as guidance for the search of the interfering wireless sources. The information collected and analyzed is obtained by a dynamic technique that integrates the acquisition of real-time GPS signal data, sensing in the spectrum of signal transmission, and capturing of 802.11 frames.With the measurement process results, the geo-location of the interfering sources are obtained and their most relevant characteristics are described.
