Ko te mita rere Doppler hongere tuwhera e pā ana ki te mita rere hongere tuwhera Doppler ultrasonic, ki te whakataurite ki te mita rere radar Doppler, he painga ēnei:
Te tika o te ine:Ka taea e te mita rere awa tuwhera Ultrasonic Doppler te ine i te tere rere o te wāhanga wai, ka taea te whakaata tika ake i te tohatoha tere rere o te wāhanga wai katoa, ā, ko te tika o te ine he ±1% teitei ake rānei. Ka ine te mita rere radar Doppler i te tere rere o te mata o te tinana wai, ahakoa ka taea te huri i te tere rere o te mata ki te tere rere toharite o te wāhanga mā te tauira kua hangaia, engari i roto i ngā āhuatanga rere uaua, i te whakamahinga tuatahi rānei o te tauwehenga whakatikatika tautuhinga tirotiro rere, he iti noa te tika.
He kaha ki te urutau ki ngā āhuatanga rere uaua: He pai ngā mita rere awa tuwhera Ultrasonic Doppler mō ngā momo āhuatanga rere, tae atu ki te wai paru, te pahuka, me te rere wai kore pumau. Nā te mea e hangai ana ki te whakaata o ngā matūriki iri i roto i te wai ki te ngaru ultrasonic hei ine i te tere rere, ahakoa he poke kei roto i te wai, he mirumiru, me ētahi atu, ka pai ake te mahi. He nui te pānga o te nekehanga o te mata wai ki te mita rere radar Doppler. Mena he nui te nekehanga o te mata wai, ka kore e pumau te tohu whakaata o te ngaru radar, ka pā ki te tika o te ine.
He iti te pānga ki te rangi: ko te mita rere Doppler tuwhera e whakauruhia ana ki raro i te wai, ki te awa rānei, kāore e pāngia e ngā huringa o te rangi, pērā i te ua nui, te hau, te kohu, me ētahi atu, he iti noa iho te tika o tana ine. Ka inehia te mita rere radar Doppler mā te tuku ngaru radar ki te mata o te wai. Ka pāngia pea te horapa me te whakaata o ngā ngaru radar e ngā āhuatanga o te rangi, hei tauira, ka pāngia pea te tohu radar e te ua nui, ā, ka nui ake te piki me te heke o te mata o te wai e ngā hau kaha, ka pāngia ai te tika o te ine.
He pai mō te aroturuki tonu mō te wā roa: Nā te mea he iti ake te pānga o ngā āhuatanga taiao ki te mita rere Doppler tuwhera-awa, ā, he pumau hoki tana mahi, he pai ake mō te aroturuki tonu mō te wā roa, mō te wā roa hoki o te rere o te awa tuwhera, ka taea ai te whakarato raraunga pumau me te pono. Tērā pea ka rerekē, ka hē rānei te mita rere radar Doppler i roto i ētahi huarere kino, i ētahi āhuatanga taiao motuhake rānei, ā, he ngoikore te pumau o te aroturuki tonu mō te wā roa.
