Operativnoe Prognozirovanie Kharakteristik Svch Radiovoln Nad Sushey Anatoliy Novikov Russian edition

Tema dannoy raboty posvyashchena probleme prognoza usloviy rasprostraneniya radiovoln santimetrovogo (3 - 30 GGts) i detsimetrovogo (300 MGts - 3 GGts) diapazonov. V nastoyashchee vremya eti diapazony ispol'zuyutsya dlya raboty bol'shinstva radiotekhnicheskikh sistem: sistem nazemnoy svyazi, sputnikovoy i kosmicheskoy svyazi, sistem radiolokatsii i radionavigatsii. Kachestvo raboty nazemnykh sistem zavisit ot usloviy rasprostraneniya radiovoln, v chastnosti, ot kharaktera mnogoluchyevosti, kotoryy, v svoyu ochered', opredelyaetsya svoystvami sredy rasprostraneniya (atmosfery i podstilayushchey poverkhnosti. Chtoby nailuchshim obrazom sproektirovat' sistemu ili gramotno izmenit' eye parametry, neobkhodim prognoz tekh kharakteristik radiovoln, kotorye vliyayut na osnovnye parametry prinimaemykh radiosignalov. Eto: polnye poteri na trasse, opredelyayushchie oslablenie radiosignala; ugly prikhoda radiovoln, dayushchie peleng na istochnik, i gruppovoe vremya zapazdyvaniya, po kotoromu otsenivaetsya zaderzhka radiosignala. V dannoy rabote privedeny sravnitel'nye rezul'taty raschyetov i izmereniy impul'snykh kharakteristik i mnozhitelya oslableniya dlya sukhoputnogo kanala rasprostraneniya radiovoln. Takzhe dany rezul'taty obrabotki meteopoley (The Cabauw mast).
