鱼群回声积分仪的功能、结构分析及模拟组装的探讨

本文对鱼群回声积分仪的理论基础及其基本功能和结构作了简要的阐述和分析。在此基础上,对利用现有的高性能鱼探仪和通用计算模拟数字式积分仪进行组装的可能性,以及如何设计一种合适的接口装置进行了探讨。

THE MAIN FUNCTIONS AND STRUCTURE OF ECHO INTEGRATOR AND THE DESIGN FOR AN ANALOG ASSEMBLY

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.
