Pehea e koho ai i ka mika pae radar? 26G a i ʻole 80G?

1. Alapine (frequency) a me ke kihi kukuna

• Radar 26 GHz:
• ʻO ka alapine haʻahaʻa e hopena i kahi kihi kukuna ākea (maʻamau 8°-10°).
• Kūpono no nā pahu wai ākea a i ʻole nā ​​​​​​hana me nā mea keakea liʻiliʻi.
• ʻOi aku ka maikaʻi no nā ana lōʻihi (a hiki i ~30-40 mika).
• Radar 80 GHz:
• Hoʻokumu ke alapine kiʻekiʻe i kahi kihi kukuna haiki (maʻamau 3°-4°).
• Kūpono no nā pahu wai haiki a i ʻole nā ​​​​​​hana me nā mea keakea, ʻoiai ke pale aku nei ke kaola haiki i nā keakea.
• Hāʻawi i ka pololei a me ka hoʻonā kiʻekiʻe aʻe, ʻoi aku hoʻi ma nā wahi pōkole.

2. Kaiapuni Noi
• Radar 26 GHz:
• Hana maikaʻi i nā noi maʻamau me ka liʻiliʻi o ke keakea.
• Hana kūpono me nā wai a me nā mea paʻa akā hiki ke pilikia me nā ʻano pahu liʻiliʻi a paʻakikī paha.
• Radar 80 GHz:
• ʻOi aku ka maikaʻi ma nā wahi paʻakikī, e like me nā pahu me nā mea hoʻonāukiuki, nā baffles, a i ʻole nā ​​​​waihoʻo.
• Hoʻohana pono i nā mea dielectric constant haʻahaʻa (e laʻa me nā hydrocarbons).
• Hana maikaʻi me nā mea paʻa, nā pauka, a i ʻole nā ​​granules ma muli o ka hoʻonā kiʻekiʻe.

3. Pae Ana
• Radar 26 GHz:
• Kākoʻo maʻamau i nā pae ana lōʻihi (e laʻa, a hiki i 40 mika no nā wai).
• He koho maikaʻi no nā pahu wai nui a i ʻole nā ​​waihona wai hāmama.
• Radar 80 GHz:
• Kūpono no nā mamao waena a lōʻihi (e laʻa, a hiki i 30 mika).
• Kūpono no nā noi kikoʻī kiʻekiʻe a i ʻole nā ​​​​​​pahu liʻiliʻi.

4. Ke kau ʻana a me ke kau ʻana
• Radar 26 GHz:
• Pono nā antennas nui aʻe ma muli o ke kihi kukuna ākea, kahi e kaupalena ai i ke kau ʻana ma nā wahi paʻa.
• ʻOi aku ka maʻalahi o ke kau ʻana i loko o nā pahu wai a i ʻole nā ​​moku hāmama.
• Radar 80 GHz:
• ʻO nā antenna liʻiliʻi a liʻiliʻi e maʻalahi ai ke kau ʻana i nā wahi paʻa.
• Kūpono no nā moku me nā pilina hana liʻiliʻi.

5. Kumukūʻai
• Radar 26 GHz:
• ʻOi aku ka liʻiliʻi o ke kumukūʻai, e lilo ia i mea kūpono no nā noi maʻamau.
• Radar 80 GHz:
• Ke kumukūʻai kiʻekiʻe ma muli o ka ʻenehana holomua, akā kūpono ia no nā noi paʻakikī a pololei paha.

I ka manawa e koho ai i kēlā me kēia

E koho i ka Radar 26 GHz inā:
• Pili ka noi i nā pahu wai nui a i ʻole nā ​​waihona wai.
• Ua emi nā mea keakea i loko o ka pahu.
• Pono ʻoe i kahi hopena kūpono no ke ana ʻana maʻamau.

E koho i ka Radar 80 GHz inā:
• He mau hakahaka haiki, nā mea keʻakeʻa, a i ʻole nā ​​​​​​hale paʻakikī ko ka pahu a i ʻole ka moku.
• He mea koʻikoʻi ka pololei a me ka pololei.
• He haʻahaʻa ka dielectric constant o ka mea a i ʻole he ʻano paʻa/granular.
• Pono ʻoe e pale i ke komo ʻana i nā wahi paʻakikī.

ʻO ka mea hope loa, pili ke koho i nā koi o kāu noi, nā kūlana o ke kaiapuni, a me ka waihona kālā. No nā hana paʻakikī loa a pololei paha, ʻoi aku ka maikaʻi o ka radar 80 GHz.
