Izicelo Ezithuthukile Ekutakuleni Izinhlekelele
Njengesizwe esikhulu kunazo zonke emhlabeni esitholakala eduze kwePacific Ring of Fire, i-Indonesia ibhekene nezinsongo eziqhubekayo zokuzamazama komhlaba, ama-tsunami, nezinye izinhlekelele zemvelo. Amasu okudala okusesha nokuhlenga ngokuvamile abonakala engasebenzi ezimeni eziyinkimbinkimbi njengokuwa okuphelele kwesakhiwo, lapho ubuchwepheshe benzwa ye-radar esekelwe kumphumela we-Doppler buhlinzeka ngezixazululo ezintsha. Ngo-2022, ithimba elihlangene labacwaningi base-Taiwanese-Indonesian lakha isistimu ye-radar ekwazi ukubona ukuphefumula kwabasindile ngezindonga zikakhonkolo, okubonisa ukugxuma kwe-quantum emandleni okuthola impilo yangemva kwenhlekelele.
Ukuqamba okusha okuyinhloko kulele ekuhlanganisweni kwayo kwe-radar ye-Frequency-Modulated Continuous Wave (FMCW) nama-algorithms okucubungula isignali athuthukisiwe. Isistimu isebenzisa ukulinganisa okubili okunembayo ukuze kunqobe ukuphazamiseka kwesignali okuvela emfucumfucwini: izilinganiso zokuqala futhi inxephezele ukuhlanekezela okubangelwa izithiyo ezinkulu, kuyilapho okwesibili kugxile ekutholeni ukunyakaza kwesifuba okucashile (ngokuvamile u-0.5-1.5 cm amplitude) kusukela ekuphefumuleni kuya ukukhomba izindawo zosindile. Ukuhlolwa kwaselabhorethri kubonisa ikhono lesistimu lokungena ezindongeni zikakhonkolo eziwugqinsi ongu-40 cm futhi libone ukuphefumula okungafika kumamitha angu-3.28 ngemuva, ngokunemba kokuma phakathi kuka-±3.375 cm – okudlula kude izinto ezijwayelekile zokuthola ukuphila.
Ukusebenza ngempumelelo kwaqinisekiswa ngezimo zokuhlenga ezilingisayo. Ngamavolontiya amane abekwe ngemuva kwezindonga zikakhonkolo ezinogqinsi oluhlukahlukene, isistimu ithole ngempumelelo zonke izimpawu zokuphefumula zezifundo, igcine ukusebenza okuthembekile ngisho nangaphansi kwesimo sodonga esingu-40 cm esiyinselele kakhulu. Le ndlela yokungathintani iqeda isidingo sokuthi abatakuli bangene ezindaweni eziyingozi, kunciphisa kakhulu izingozi zesibili zokulimala. Ngokungafani nezindlela zendabuko ze-acoustic, infrared noma optical, irada ye-Doppler isebenza ngaphandle kobumnyama, intuthu noma umsindo, ivumela ukusebenza okungu-24/7 phakathi newindi elibalulekile lokuhlenga “amahora angu-72” abalulekile.
