단일 수신 하이드로폰을 이용한 음원 추적 기술과 수중로봇 항법 응용

Abstract

This study analyzed the signal processing parameters of the field differencing method for estimating the source velocity (range) using a single hydrophone. In order to prevent the method from producing incorrect results, it is important toproperly understand the role and constraints of its processing parameters. The constraints and performance trade-offs of the processing parameters were analyzed and exemplified using the SWellEX-96 experiment data.
