Abstract: [cze] [eng]
TESTCOM ve spolupráci s Ústavem fyziky atmosféry AV ČR zahájil v prosinci 2000 experimentální průzkum šíření elektromagnetických vln v kmitočtovém pásmu 58 GHz na experimentálním skoku Geofyzikální ústav AV ČR Praha - TESTCOM. Průzkum je zaměřen na získání znalostí o únicích způsobených hydrometeory v tomto kmitočtovém pásmu v našich klimatickýchpodmínkách. Skok je dlouhý 846 m, kmitočet je 57 650 MHz a polarizace je vertikální. TESTCOM and Institute of Atmospheric Physics, ASCR launched a common experimental research in the frequency band 58 GHz on the experimental hop Geophysical Institute, ASCR - TESTCOM in the frequency band 58 GHz since December 2000. Our research has been focused on obtaining knowledge concerning attenuation due to hydrometeors in our specific climatic conditions. The path length is 846 m, used frequency is 57 650 MHz with V polarization. Records of received signal were statistical processed and cumulative distributions of attenuation due to hydrometeors for individual month as well as the first year period of observation from December 2000 to November 2001 were obtained. The records of attenuation were compared with the concurrent meteorological situation and attenuation due to rain, snow, fog, rain with snow and rain with hail were separatd. Rain intensities have been measured at both sites of path. Obtained CDs of rain intensities are presented.
