Ngenxa yokwanda ngokukhawuleza kwenani lezithuthi zasezidolophini, ulawulo lweendawo zokupaka zemveli lujongene nemiba efana nokusebenza okuphantsi kunye nokuchithwa kwezixhobo. Izinzwa ze-Ultrasonic zinokuphucula kakhulu ukusebenza kakuhle kokupaka kunye nolawulo lweendawo zokupaka ngokujonga imeko yokuhlala ngexesha langempela.
Izinzwa ze-ultrasonic zisebenza ngokomgaqo wokubonakaliswa kwamaza esandi. I-transmitter ikhupha ii-pulses ze-ultrasonic eziphindaphindayo, ezibonisa imiqobo (njengezithuthi) kwaye zibuyele kwi-receiver. Ngokubala umahluko wexesha lokuba amaza esandi ahambe aye nabuya kwinto ethile, inkqubo ilinganisa ngokuchanekileyo umgama.
Xa imoto ingena kwindawo yokupaka, i-sensor iyayibona inguqu kumgama ize ivuselele uhlaziyo lwesimo. Le ndlela yokulinganisa ngaphandle kokuthintana ithintela ukuguguleka komzimba kwaye ifanelekile kwiindawo ezintsonkothileyo.
Inkqubo yokupaka ekrelekrele imisela imeko yendawo yokupaka ngokusebenzisa imida esekiweyo. Ukuba amaza e-ultrasonic akhutshwa yi-sensor "adlula ngokukhululekileyo" ngaphakathi koluhlu olumiselweyo, indawo ichongwa njengengenanto. Ngokwahlukileyo koko, ukuba amaza e-ultrasonic "avaliwe" ngaphakathi koluhlu olumiselweyo, indawo ichongwa njengengenanto. Iziphumo zidluliselwa ngexesha langempela ngezibane zesalathisi (umthubi kwindawo enabantu, oluhlaza kwindawo engenanto) kunye nesikrini esiphakathi, ukuqinisekisa ukuba abaqhubi kunye nabalawuli banokufikelela kulwazi ngokukhawuleza.
Ukujongana nokuphazamiseka kokukhanya okubangelwa ziindonga, umphezulu womhlaba, izithuthi ezikufutshane, njl.njl., ii-sensors ze-ultrasonic azifuni nje kuphela ingqalelo enzulu kwindawo yokufaka kodwa zikwasebenzisa ii-algorithms eziphambili ezifana ne-**time gating** kunye ne-**beamforming** ukunciphisa iimpazamo zokufumanisa. Xa ukhetha ii-sensors, kuyacetyiswa ukuba ukhethe iimodeli ezine-**engile ye-beam emxinwa** ukuze uphephe ukufunyanwa okungachanekanga okubangelwa yi-engile ye-beam ebanzi kakhulu. Ukongeza, ukusebenzisa uphawu lwe-**synchronization** lwee-sensors ze-ultrasonic kuqinisekisa ukuba nokuba zifakwe ecaleni, azichaphazeleki ngamaza esandi akhutshwayo omnye komnye. Ngokusebenzisa ii-sensors ezininzi ukuze zisebenze ngokubambisana, ukugweba okungachanekanga ngenxa yeminye imiqobo kunokunciphisa kakhulu.
