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.In an acoustic transceiver, a target region detector of a receiver generates signal intensity data of echo signals picked up by individual receiver beams and determines the addresses of the detected target. The target region detector causes the signal intensity data to be saturated to a certain extent while maintaining information about the target directions. The quantitative data detector of the receiver also generates signal intensity data of the echo signals for individual directions of the received rays, but does not cause the signal intensity data to be saturated. A data synthesizer sends signal intensity data and fish quantity data obtained by integrating the signal intensity data from the quantitative data detector based on address information from the target area detector to a screen portion. The display portion presents an echo sound image based on the signal intensity data obtained by the target area detector along with fish quantity data for a fish estimate in each target area obtained by the quantitative data detector.
