Ngā Hua Pūihi Pūwero Porowhita RFMISOC

Hītori o te pūihi haona porowhita-polarized

He momo pūihi nui te pūihi porowhita porowhita, he whānuitia ana ngā whakamahinga, tae atu ki ngā whakawhitiwhiti kōrero, te radar, ngā whakawhitiwhiti kōrero amiorangi me te ine reo irirangi. E whai ake nei he whakataki hītori ki ngā pūihi porowhita porowhita:

Mai i te mutunga o te tekau tau atu i 1940 ki te tīmatanga o te tekau tau atu i 1950, ka tīmata te puta o te ariā me te hoahoa o ngā pūihi porowhita porowhita. I tēnei wā, ka tīmata ngā kaihanga pūihi ki te mōhio he iti noa ngā herenga o ngā pūihi porowhita tuku iho i roto i ētahi whakamahinga. Nō reira, ka tīmata rātou ki te rangahau me te tūhura i te ariā o ngā pūihi porowhita kia pai ake ai te tuku me te whiwhi tohu.

I te tau 1958, i hangaia e Paul G. Montgomery, he miihini i Radar Systems Corporation i te Hononga o Amerika, tētahi pūihi haona me ngā āhuatanga porowhita porowhita, e kiia nei ko te Montgomery Antenna. Koinei te whakatinanatanga angitu tuatahi o tētahi pūihi haona porowhita porowhita, ā, i kukume mai i te aro me te rangahau whānui.

I ngā tekau tau i muri mai, kua rangahaua whānuitia, kua whakawhanakehia hoki ngā pūihi haona porowhita-porowhita. Kua whakahaerehia e ngā kaihangarau he maha ngā whakamātautau me ngā tātaritanga ariā hei hoahoa me te arotau i te hanganga me te mahi o ngā pūihi haona porowhita-porowhita.

I ngā tau 1960, i whānuitia te whakamahinga o ngā pūihi haona porowhita-porowhita i roto i te ao whakawhitiwhiti kōrero. Ko te painga o te pūihi haona porowhita-porowhita he pai ake te kapinga tohu me te ārai i te pokanoa, ā, he tino pai mō ngā taiao horapa maha-ara i roto i ngā pūnaha whakawhitiwhiti kōrero ahokore.

I ngā tau 1980 me 1990, me te whanaketanga tonu o ngā whakawhitiwhiti kōrero amiorangi me te hangarau radar, ka whānui ake te whānuitanga o ngā tono mō ngā pūihi haona porowhita-polarized. He whānuitia te whakamahinga o ngā pūihi haona porowhita-polarized i roto i ngā teihana whenua whakawhitiwhiti kōrero amiorangi, ngā pūnaha radar, me ngā mara hōia me te rererangi.

I te whanaketanga tonu o te hangarau hiko, kua pai ake hoki te hoahoa me te tukanga hanga o ngā pūihi haona porowhita-porowhita. Ka whakamahia e ngā pūihi haona porowhita-porowhita hou ngā rauemi matatau me ngā tikanga hanga hei whakarato i ngā awhe auau mahi teitei ake, te mahi pai ake me ngā rahi iti ake.

Me pēhea te mahi a te pūihi haona porowhita-polarized

Ka tutuki i ngā pūihi haona porowhita-porowhita ngā āhuatanga hihi porowhita-porowhita nā roto i ō rātou āhuahanga me te hoahoa motuhake. Ko te kaupapa mahi o tēnei pūihi e hangai ana ki ngā āhuatanga matua e whai ake nei:

Āhua o te pū: Ko ngā pūihi pūihi porowhita porowhita e whakamahi ana i te hanganga pūwhakaata āhua pū. Mā te hoahoa o te pūihi pūihi ka horapa tonu te tohu ki roto i te pū, ka hangaia he āhuatanga irahiko motuhake ka taea te whakatutuki i ngā whakaritenga o te porowhita porowhita.

Hononga-whakawhiti: He hononga-whakawhiti motuhake ka tāutahia ki roto i te pūihi haona hei hono i ngā wāhanga hiko whakapae me te poutū me te rerekētanga ā-wāhanga o te 90 nekehanga. Mā tēnei hoahoa ka taea e te pūihi te whakaputa i tētahi tauira irahiko porowhita-polarized.

Irahiko maha-aratau: Mā te hoahoa o tētahi pūihi haona porowhita-porowhita ka taea te tuku i ngā momo maha o ngā mara hikohiko i te wā kotahi, tae atu ki ngā tohu porowhita-porowhita-porowhita e hurihia ana i ngā ahunga porowhita rerekē.

I tēnei wā, e whakamahia whānuitia ana ngā pūihi haona porowhita porowhita i roto i ngā momo whakamahinga, tae atu ki ngā whakawhitiwhiti kōrero amiorangi, ngā whakawhitiwhiti kōrero pūkoro, te ine reo irirangi, te rererangi, te radar, me ngā waka rererangi kore.
