Four Years of Total Attenuation Statistics of Earth-Space Propagation Experiments at Ka-Band in Toulouse PROJECT TITLE :Four Years of Total Attenuation Statistics of Earth-Space Propagation Experiments at Ka-Band in ToulouseABSTRACT:The Ka-band propagation experiments conducted by ONERA in Toulouse (forty three.57°E, 1.forty seven°N) in the southwest of France started in 2009 and remains on-going. The equipment comprises a beacon Earth station, a profiling radiometer, and a rain gauge. The ground station measures the received beacon signal employing a ten-Hz sampling rate. The profiling radiometer measures the sky brightness temperatures at 5 Ka-band and seven V-band channels, surface temperature, surface humidity, and surface pressure. From July 2009 to March 201one, the beacon receiver recorded the 19.7-GHz (horizontal polarization) HotBird 6 beacon signal along a slant path of 38.vi° of elevation angle. Since April 2011, the beacon receiver has been recording the twenty.a pair of-GHz (vertical polarization) Astra 3B beacon signal along a slant path of thirty five.1° of elevation angle. This paper aims at providing a complete description of the ONERA Information Processing Tool (in particular the methodology followed to retrieve total attenuation) used to compute 4 years (from July 2009 to June 2013) of copolar attenuation statistics. The experimental setup and therefore the characteristics of the Earth-house links are briefly described. The complementary cumulative distribution operate (CCDF) of total attenuation for the whole amount is presented and compared with ITU-R recommendations. The measured CCDF of the rainfall rate is computed and compared with ITU-R Rec. P.837 and can additionally be used as input for the rain attenuation model given in ITU-R Rec. P.618. The measured CCDFs of total attenuation duration and total attenuation slope are also presented. Did you like this research project? To get this research project Guidelines, Training and Code...
