THE MAIN FUNCTIONS AND STRUCTURE OF ECHO INTEGRATOR AND THE DESIGN FOR AN ANALOG ASSEMBLY
Abstract:
Acoustic technique used for fish stock assessment is an efficient method developed by Norwe gian scientists about 30 years ago and has been attached great attention by FAQ and ICES and the like. Now it has been one of the regular means for stock survey in advanced fisheries countries. In this paper, the basic theory of echo integration and the main functions and structure of integrator are briefly described and analysed, based on which, the possibility of analog assembly of integrator by means of existing high quality echo-sounder together with digital computer, and how to design an appropriate interface device are approached.
