Te ine i te whānui o te raina taiaho
He maha ngā tikanga mō te inewhānui raina taiaho:
1. Ina nui te whānui o te rārangi taiaho (> 10 GHz, ina maha ngā momo wiri i roto i ngā kaiwhakaoho taiaho maha), ka taea te whakamahi i ngā inenga matawhenua tuku iho e whakamahi ana i ngā whariki diffraction hei ine. Heoi, he uaua tēnei tikanga ki te whakatutuki i te taumira auau teitei.
2. Ko tētahi atu tikanga ko te whakamahi i tētahi tātari auau hei huri i ngā piki me ngā heke o te auau hei tātari kaha. Ka taea te tātari he ine taurite kore, he kōhao tohutoro tino tika rānei. He iti hoki te taumira o tēnei tikanga ine.
3. Ko ngā taiaho auau-kotahi te tikanga heterodyne e whakamahia ana, e tuhi ana i te auau patu o te auau putanga taiaho me tōna ake auau i muri i te taupatupatu me te whakaroa.
4. Mō ngā whānui raina o ētahi rau hertz, he uaua te whakamahi i te tikanga heterodyne tuku iho nā te mea e hiahiatia ana he roa roa o te whakaroa. Ka taea te whakamahi i te muka koropiko me te whakakaha muka kua hangaia hei whakaroa i te roa o te whakaroa.
5. Mā te tuhi i te auau patu o ngā taiaho motuhake e rua, ka taea te whakatutuki i te taumira tino teitei. I tēnei wā, he iti iho te haruru o te taiaho tohutoro i tō terēseri inehia, he rite rānei ā rātou tohu mahi. Ka taea te whakamahi i ngā koropiko raka, i ngā tikanga rānei i runga i te tuhi pāngarau hei tatau i te rerekētanga auau inamata. He tino māmā, he pumau hoki tēnei tikanga, engari me whai i tētahi atu taiaho (me te auau e tata ana ki terēseri inehiaMena he whānui te whānuitanga o te whānuitanga o te ine, he tino watea te whakamahi i te heru auau.
Ko te ine i te auau whatu me whakarato i tētahi tohutoro auau (wā rānei) motuhake i tētahi wāhi.ngā taiaho whānui-rārangi whaiti, kotahi noa te hihi tohutoro e hiahiatia ana hei whakarato i te tohutoro tika. Mā te tikanga heterodyne ka whiwhi i te tohutoro auau mā te whakamahi i tētahi whakaroa roa ki te taputapu whakamātautau tonu. Ko te mea pai, me karo te ōritetanga wā i waenga i te hihi tīmatanga me tōna hihi whakaroa. Nō reira, ko ngā muka whatu roa te nuinga o te wā e whakamahia ana. Heoi, nā te piki me te heke pumau me ngā pānga oro, ka puta mai i ngā muka whatu roa he haruru wāhanga tāpiri.
