Ka LekiōʻO ka ʻenehana (RF) kahi ʻenehana kamaʻilio uea, hoʻohana nui ʻia i ka lekiō, kamaʻilio, radar, kaohi mamao, nā ʻenehana ʻike uila a me nā kahua ʻē aʻe. Hoʻokumu ʻia ke kumu o ka ʻenehana lekiō uila uila i ka hoʻolaha a me ka modulation a me ka ʻenehana demodulation o nā hawewe electromagnetic. Ma lalo wau e hoʻolauna iā ʻoe i ke kumumanaʻo o ka ʻenehana uila uila uila.
Nā loina loea
ʻO ka ʻenehana lekiō uila uila he ʻenehana e hoʻohana ana i nā nalu lekiō no ke kamaʻilio. ʻO nā hawewe lekiō he ʻano ʻano hawewe electromagnetic me nā alapine kikoʻī a me nā pae. Ma ka leka uila uila uila, hoʻololi ka hopena hoʻouna i nā hōʻailona ʻike i nā hōʻailona hawewe electromagnetic ma o nā nalu lekiō a hoʻouna iā lākou i waho. Loaʻa i ka hopena e loaʻa nā hōʻailona hawewe electromagnetic a laila hoʻololi iā lākou i mau hōʻailona ʻike e hoʻokō ai i ka hoʻoili ʻikepili a me ke kamaʻilio.
Lekiō alapinepine e loaʻa a me ka hoʻouna kaapuni kumu
ʻO nā loina o ka ʻenehana lekiō uila uila ka mea nui i kēia mau ʻano:
Hoʻololi pinepine: Ma nā leka uila uila uila, ua hoʻololi ʻia nā hōʻailona ʻike i nā hōʻailona nalu electromagnetic o nā alapine kūikawā e pili ana i ka ʻenehana modulation. ʻO nā ʻano hoʻohui maʻamau ʻo ia ka amplitude modulation blending (AM), frequency modulation blending (FM), a me ka phase modulation blending (PM).
Antenna: Antennahe mea koʻikoʻi i ka launa pū ʻana o ka lekiō uila. Hoʻohana ʻia ia e hoʻouna a loaʻa i nā hōʻailona nalu. Hoʻopili ka hoʻolālā a me ke kau ʻana o nā antenna i ka mamao o ka hoʻouna ʻana a me ka maikaʻi o nā kamaʻilio kelepona.

Antenna Puka Kiwi Maʻamau (4.90-7.05GHz)
Antenna Kiwi Polarized ʻElua Conical (2-18GHz)
RF Misoantenna huahana paipai
Kaila coding a me ka decoding: Ma nā leka uila uila uila, hoʻohana ʻia ke kahawai coding a me ka ʻenehana decoding no ka hoʻomaikaʻi ʻana i ke kūpaʻa a me ka anti-interference o ke kamaʻilio a hōʻoia i ka pololei o ka kamaʻilio ʻikepili.
Mana mana: Pono ke kama'ilio lekiō uila e ho'ololi i ka mana pana e hō'oia e hiki ke ho'ouna 'ia ka hō'ailona i loko o kekahi laulā a pale i ka ho'opili 'ana i kekahi.
ʻO ka hoʻokele band frequency: Pono e hoʻokele pono i nā kumuwaiwai spectrum ke kamaʻilio ʻana i ka lekiō uila e pale aku i ka hopena o nā kumuwaiwai alapine i pau a hōʻoia i ka paʻa a me ka hilinaʻi o ke kamaʻilio.
Nā hiʻohiʻona noiʻi
Hoʻohana nui ʻia ka ʻenehana alapine lekiō ʻole i ka nohona o kēia wā, e hāʻawi ana i nā mea leʻaleʻa a me nā mea hou no ke ola o ka poʻe a me ka hana. Eia kekahi mau wahi noi uila RF maʻamau:
Nā kelepona paʻalima: ʻO ke kumu o ke kamaʻilio kelepona ʻana ʻo ia ka ʻenehana alapine lekiō, me nā kelepona paʻa lima, nā ʻupena uila, nā leka uila, a me nā mea ʻē aʻe.
Home akamai: I loko o nā ʻōnaehana home akamai, e like me nā laka puka akamai, nā mana kukui akamai, nā lako hale akamai, a me nā mea ʻē aʻe, hiki ke hoʻokō ʻia ka mana mamao a me ka hoʻokele naʻauao ma o ka ʻenehana uila.
Pūnaewele o na mea: He mea koʻikoʻi ka ʻenehana lekiō uila ʻole o ka Pūnaewele o nā Mea. Hoʻomaopopo ʻo ia i ka pilina ma waena o nā polokalamu ma o nā ʻenehana sensor uila a ʻike i ka nānā ʻana naʻauao, ʻohi ʻikepili a me ka mana mamao.
Pūnaehana ʻike uila: I loko o nā pūnaewele sensor uila, hoʻohana nui ʻia i ka nānā ʻana i ke kaiapuni, ke olakino olakino, ka mana ʻoihana a me nā kahua ʻē aʻe e hoʻokō ai i ka hōʻiliʻili ʻikepili a me ka nānā ʻana i ka manawa maoli.
ʻO nā lako hoʻomalu mamao ʻole: Hoʻohana nui ʻia ka ʻenehana lekiō uila ʻole i nā panela hoʻomalu e like me nā mana mamao TV, nā mea hoʻokele kaʻa, a me nā mea hoʻohālike e hoʻopau i nā hana mamao.
Pūnaehana radar: LekiōHe kuleana koʻikoʻi ka ʻenehana alapine i nā ʻōnaehana radar a hoʻohana ʻia no ka ʻike maka, ka nānā ʻana a me ka hoʻokele. Hoʻohana nui ʻia ia i ka aerospace, meteorology a me nā māla ʻē aʻe.
ʻO nā noi o ka ʻenehana uila uila uila he ākea loa, e uhi ana i nā kahua he nui, e like me ke kamaʻilio kelepona, nā leka uila, nā ʻōnaehana radar, nā mana mamao, nā ʻenehana ʻike uila, a me nā mea ʻē aʻe. he kuleana koʻikoʻi ma nā ʻano hana like ʻole, e lawe mai i ka ʻoluʻolu a me ka hana hou i ke ola a me ka hana o nā kānaka.
No ka 'ike hou aku, e kipa mai:
