Abstract

Sonarsystem som innbefatter i det minste en sender og en fleksibel antenne innbefattende et flertall av seksjoner festet en etter en etter hverandre, der hver seksjon er anordnet med i det minste én akustisk mottaker. Systemet er utstyrt med posisjonsinnretninger som gjør det mulig å bestemme den instantane posisjonen til hver mottaker og beregningsenhet som gjør det mulig å rekonstruere et bilde av sjøbunnen ved å ta hensyn til de instantane mikrobevegelsene til hver av mottakerne.
