Ahịrị mgbasa ozi nke ultrashort wave na microwave

Ebili mmiri nke Ultrashort, karịsịa microwaves, nwere nnukwu frequency na mkpụmkpụ wavelength, na ebili mmiri nke ala ha na-ebelata ngwa ngwa, n'ihi ya, ha enweghị ike ịdabere na ebili mmiri nke ala maka ịgbasa ogologo oge.

A na-agbasa ebili mmiri Ultrashort, ọkachasị microwaves, site na ebili mmiri oghere.N'ikwu ya n'ụzọ dị mfe, ikuku oghere bụ ebili mmiri na-agbasa n'ahịrị kwụ ọtọ n'ime oghere.N'ụzọ doro anya, n'ihi curvature nke ụwa, enwere oke ahịrị-anya anya Rmax maka ịgbasa ebili mmiri.A na-akpọkarị ebe dị n'ime ebe dị anya na-ahụ anya ebe ọkụ;mpaghara gafere oke anya anya kpọmkwem RMax ka a na-akpọ mpaghara onyinyo.Ọ na-aga n'ekwughị na mgbe ị na-eji ultrashort wave na microwave maka nzikọrịta ozi, ebe nnabata kwesịrị ịdaba n'ime oke anya anya nke Rmax nke antenna na-ebufe.

N'ịbụ nke na-emetụta radius nke curvature nke ụwa, mmekọrịta dị n'etiti oke anya anya nke anya Rmax na HT dị elu na HR nke antenna na-ebufe na antenna na-anata bụ: Rmax＝3.57{√HT (m) +√HR ( m)} (km)

N'iburu n'uche mmetụta ntugharị nke ikuku na ebili mmiri redio, a ga-edozi oke anya nke anya ka Rmax = 4.12{√HT (m) +√HR (m)}(km) Ebe ọ bụ na ebili mmiri electromagnetic dị ukwuu. dị ala karịa nke ebili mmiri ọkụ, mgbasawanye nke ebili mmiri redio dị irè Ogologo nlele anya Re bụ ihe dịka 70% nke oke nlele anya Rmax, ya bụ, Re = 0.7 Rmax.

Dịka ọmụmaatụ, HT na HR bụ 49 m na 1.7 m n'otu n'otu, mgbe ahụ, ebe anya anya nke ọma bụ Re = 24 km.
