I ka honua o ka ʻenehana radar, ua hoʻololi ka hoʻomohala ʻana o nā ʻōnaehana radar array i ke ala a mākou e ʻike ai a hahai i nā mea i ka lewa. Hāʻawi kēia mau ʻōnaehana i ka maʻalahi, hoʻomaikaʻi i ka hana, a me nā mea hiki ke hoʻohālikelike ʻia me nā ʻōnaehana radar maʻamau. ʻO kahi mea nui i kōkua i ka holomua o ka ʻenehana radar phased array ʻo ka microstrip circulator.
Hoʻohana nā ʻōnaehana radar i nā ʻāpana he nui e hoʻouna a loaʻa i nā hōʻailona alapine. Hoʻonohonoho ʻia kēia mau antenna i kahi hoʻonohonoho hoʻonohonoho hoʻonohonoho, e ʻae ana i ka hoʻokele uila uila a me ka beamforming. ʻO kēia ka mea e hiki ai i ka ʻōnaehana radar ke nānā wikiwiki i ka lewa a puni, e hahai i nā pahuhopu he nui i ka manawa like, a hoʻololi i nā koi o ka hana.
He mea koʻikoʻi ka microstrip circulator i loko o ka ʻōnaehana radar array phased. ʻO ia kahi mea passive, non-reciprocal e hiki ai ke hoʻokele pono i nā hōʻailona RF i loko o ka ʻōnaehana radar. Hoʻomaopopo ka circulator e kuhikuhi ʻia nā hōʻailona i hoʻouna ʻia i nā antennas no ka hoʻouna ʻana a ua hoʻouna ʻia nā hōʻailona i loaʻa i ka mea hoʻokipa no ka hana ʻana. Pono kēia hana no ka mālama pono ʻana i ka hana o ka ʻōnaehana radar a hoʻonui i kāna hana.
ʻO kekahi o nā pōmaikaʻi koʻikoʻi o ka hoʻohana ʻana i nā microstrip circulators i nā ʻōnaehana radar array phased ʻo ko lākou nui compact a me ke kaumaha haʻahaʻa. Nui a kaumaha nā circulators kuʻuna, no laila ʻaʻole kūpono lākou no ka hoʻohui ʻana i nā ʻōnaehana radar hou e hoʻokumu i ka portability a me ka neʻe. ʻO nā microstrip circulators, ma ka ʻaoʻao ʻē aʻe, ua hoʻolālā ʻia e maʻalahi a paʻakikī, e hana maikaʻi iā lākou no ka hoʻohana ʻana i nā ʻōnaehana radar array phased i kau ʻia ma nā paepae kelepona e like me nā mokulele, nā moku, a me nā kaʻa honua.
Eia kekahi, hāʻawi nā microstrip circulators i nā hiʻohiʻona hana maikaʻi loa, me ka nalowale o ka hoʻokomo haʻahaʻa, kahi kaʻawale kiʻekiʻe, a me ka bandwidth ākea. He mea koʻikoʻi kēia mau hiʻohiʻona no ka hōʻoia ʻana i ka lawe ʻana a me ka loaʻa ʻana o nā hōʻailona RF i loko o ka ʻōnaehana radar. ʻO ka poho hoʻokomo haʻahaʻa e hōʻemi i ka nalowale o ka mana hōʻailona i ka wā e hele ai i ka circulator, ʻoiai ke kaʻawale kiʻekiʻe e pale i ka leakage hōʻailona makemake ʻole, e hōʻoiaʻiʻo ana i ka pono o ka hana o ka ʻōnaehana radar. Hoʻohui ʻia, hiki i ka bandwidth ākea ākea ke hana i ka ʻōnaehana radar ma waena o kahi ākea o nā alapine, e hoʻololi a maʻalahi i nā ʻano hana like ʻole.
ʻO ka hoʻohui ʻana o nā microstrip circulators i loko o nā ʻōnaehana radar array phased ua kōkua pū i ka holomua o ka ʻenehana radar, hiki ke hoʻonui i nā mana e like me ke kaua uila, ka ʻike maka, a me ka pololei ʻimi. ʻO ke ʻano like ʻole o ka circulator e hiki ai ke hoʻokō i nā ʻenehana hana hōʻailona kiʻekiʻe, e like me ka agility pinepine a me ka ʻokoʻa polarization, he mea nui ia no nā ʻōnaehana radar hou e kūʻē i nā countermeasures uila a mālama i ka hana pono i nā kaiapuni electromagnetic paʻakikī.
I ka hopena, ʻo ka hoʻohui ʻana o nā microstrip circulators i nā ʻōnaehana radar array phased i hoʻonui nui i ka hiki a me ka hana o ka ʻenehana radar. ʻO kēia mau mea paʻa, māmā, a me nā mea hana kiʻekiʻe i hiki ke hoʻomohala i nā ʻōnaehana radar maʻalahi e hāʻawi i ka maʻalahi i hoʻonui ʻia, hoʻomaikaʻi maikaʻi ʻana i ka hana, a me nā hiki ke nānā i nā pahuhopu kiʻekiʻe. Ke hoʻomau nei ka noi no nā ʻōnaehana radar holomua, ʻo ke kuleana o nā microstrip circulators i ka hoʻolālā ʻana i ka wā e hiki mai ana o ka ʻenehana radar e mau loa i ka pivotal.
