Iwashi noma isibali sikhathi sisetshenziselwa ukuvumelanisa ama-transducer pulses nokuhlinzeka ngokulinganiswa kwebanga. Ukucutshungulwa kwesignali kukhiqiza isibonisi se-waveform esibonisa ubude besiginali ngokumelene nesikhathi esikalini esilinganisiwe, ama-algorithms okucubungula edijithali ahlanganisa ibanga nokulungiswa kwe-amplitude kanye nezibalo ze-trigonometric zemizila yomsindo ene-engeli. Amasango e-alamu aqapha amaleveli esignali ezindaweni ezikhethiwe kusitimela esinyakazayo futhi ifulegi linanela kusuka kumaphutha. Izikrini ezinemibukiso enemibala eminingi zilinganiswa ngamayunithi okujula noma ibanga. Abagawuli bedatha bangaphakathi barekhoda i-waveform ephelele nolwazi lokusetha oluhlotshaniswa nokuhlolwa ngakunye, ulwazi olufana ne-echo amplitude, ukujula noma ukufundwa kwebanga, ukuba khona noma ukungabikho kwezimo ze-alamu. Ukutholwa kwamaphutha e-Ultrasonic ngokuyisisekelo kuyindlela yokuqhathanisa. Esebenzisa izindinganiso ezifanele zereferensi kanye nolwazi lokusabalala kwegagasi lomsindo kanye nezinqubo zokuhlola ezamukelwa ngokuvamile, opharetha oqeqeshiwe uhlonza amaphethini athile e-echo ahambisana nempendulo ye-echo evela ezingxenyeni ezinhle kanye namaphutha amelelayo. Iphethini ye-echo evela ezintweni ezihloliwe noma umkhiqizo ingase iqhathaniswe namaphethini asuka kulawa mazinga okulinganisa ukuze kunqunywe isimo sayo. I-echo eyandulela i-backwall echo isho ukuba khona kokuqhekeka kwe-laminar noma i-void. Ukuhlaziywa kwe-echo eveziwe kwembula ukujula, ubukhulu, nokuma kwesakhiwo. Kwezinye izimo ukuhlolwa kwenziwa ngemodi yokudlulisela. Esimeni esinjalo amandla omsindo ahamba phakathi kwama-transducer amabili abekwe ezinhlangothini eziphambene zesiqephu sokuhlola. Uma kukhona iphutha elikhulu endleleni yomsindo, i-beam izovinjelwa futhi umsindo ngeke ufinyelele kumamukeli. Imifantu namaphutha ancikene nendawo yokuhlola, noma etshekile maqondana naleyo ndawo, ngokuvamile ayibonakali ngamasu okuhlola amapulangwe aqondile ngenxa yokuma kwawo ngokuphathelene nensimbi yomsindo. Ezimweni ezinjalo ezivamile ezakhiweni ezishiselwe, kusetshenziswa amasu e-engeli ye-engeli, kusetshenziswa ama-transducer e-engeli evamile noma ama-transducer ocwilisa aqondaniswe ukuze kuqondiswe amandla omsindo esiqeshini sokuhlola nge-engeli ekhethiwe. Njengoba i-engeli ye-wave longitudinal yesigameko ikhuphuka ngokuphathelene nendawo engaphezulu, ingxenye ekhulayo yamandla omsindo iguqulwa ibe igagasi lokugunda endaweni yesibili. Uma i-engeli iphakeme ngokwanele, wonke amandla ento yesibili azoba sesimweni samagagasi okugunda. Ukudluliswa kwamandla kusebenza kahle kakhulu kuma-engeli esigameko akhiqiza amagagasi okugunda ngensimbi nezinto ezifanayo. Ukwengeza, ukulungiswa kosayizi omncane wephutha kuthuthukiswa ngokusetshenziswa kwamagagasi e-shear, njengoba ngezikhathi ezithile, ubude begagasi begagasi lokugunda bucishe bube ngu-60% ubude begagasi obuqhathanisekayo be-longitudinal. I-angled sound beam izwela kakhulu emifantwini encike endaweni ekude yocezu lokuhlola futhi, ngemva kokugxuma ohlangothini olukude izwela kakhulu emifantwini encike endaweni yokuhlangana.
