Abstract

I en akustisk transceiver genererer en målregiondetektor av en mottaker signalintensitetsdata av ekkosignaler plukket opp av individuelle mottakerstråler og bestemmer adressene til det påviste mål. Målregiondetektoren får signalintensitetsdataene til å mettes til en viss utstrekning og samtidig opprettholde informasjon om målenes retninger. Den kvantitative datadetektor av mottakeren genererer også signalintensitetsdata av ekkosignalene for individuelle retninger av de mottatte stråler, men får ikke signalintensitetsdataene til å mettes. En datasyntetiserer sender signalintensitetsdata og fiskekvantitetsdata oppnådd ved å integrere signalintensitetsdataene fra den kvantitative datadetektor basert på adresseinformasjon fra målområdedetektoren til en skjermdel. Skjenndelen presenterer et ekko-lydbilde basert på signalintensitetsdataene oppnådd av målområdedetektoren sammen med fiskekvantitetsdata for en fiskestim i hvert målområde oppnådd av den kvantitative datadetektor.
