Abstract
Fremgangsmåte og apparat for å registrere objekter (2), særlig miner som er lagt ut i et terrengområde (l). Flere akustiske transduktorer (4.1, ... 4.i, ... 4.n) brukes for å sende ut en kort akustisk puls med en første bestemt optimal arbeids frekvens, hvoretter det utføres k signalreverseringer for de mottatte ekkosignaler fra terrengområdet (1) eller objektene (2) i dette, for å fokusere registreringen av et første objekt. De transduktorer (4) som har tilnærmet samme lydbølgeutbredelsestid frem til et reflekterende objekt og tilbake velges ut, og det fastlegges minst en lokaliseringsretning (D) som sammen- faller med midtlinjen mellom de to trans- duktorer i paret med tilnærmet samme bølgeutbredelsestid.
