I-Frequency modulated continuous wave (FMCW) yamukelwa kunsimbi yeleveli ye-radar (80G). I-antenna idlulisa isignali ye-radar eguquguqukayo nemvamisa ephezulu.
Imvamisa yesiginali ye-radar ikhuphuka ngokulandelana. isignali ye-radar edlulisiwe ibonakala nge-dielectric ukuze ikalwe futhi yamukelwe ngothi. ngesikhathi esifanayo, umehluko phakathi kwemvamisa yesignali edlulisiwe kanye neyesiginali eyamukelwe ilingana nebanga elilinganisiwe.
Ngakho-ke, ibanga libalwa nge-spectrum esuselwe kumehluko wefrikhwensi yokuguqulwa kwe-analog-to-digital kanye ne-fast fourier transform (FFT)
(1)Ngokususelwe ku-chip yefrikhwensi yomsakazo ozithuthukisele yona ukuze kuzuzwe ukwakheka kwefrikhwensi yomsakazo ohlangene;
(2) Isilinganiso esiphezulu sesignali-kuya-nomsindo, cishe esingathinteki ngokuguquguquka kwezinga;
(3) Ukunemba kwesilinganiso ukunemba kweleveli yemilimitha (1mm), engasetshenziselwa ukulinganisa izinga le-metrology;
(4) Indawo eyimpumputhe yokulinganisa incane (3cm), futhi umphumela wokulinganisa izinga loketshezi lamathangi amancane okugcina ungcono;
(5) I-engeli ye-beam ingafinyelela ku-3 °, futhi amandla agxile kakhulu, ngokuphumelelayo ukugwema ukuphazamiseka kwe-echo yamanga;
(6) Isignali yefrikhwensi ephezulu, ingalinganisa ngempumelelo izinga le-medium ne-low dielectric constant (ε≥1.5);
(7) Ukumelana nokuphazamiseka okuqinile, okucishe kungathinteki ngenxa yothuli, umusi, izinga lokushisa noshintsho lwengcindezi;
(8) I-antenna ithatha ilensi ye-PTFE, eyi-anti-corrosion esebenzayo kanye ne-anti-hanging material;
(9) Sekela ukulungisa amaphutha okukude nokuthuthukiswa okukude, ukunciphisa isikhathi sokulinda futhi uthuthukise ukusebenza kahle komsebenzi;
(10) Isekela ukulungisa iphutha kwe-Bluetooth kwefoni ephathekayo, elungele umsebenzi wokulungisa wabasebenzi abasendaweni.
