센서배열 및 CHIRP 신호처리 기법을 적용한 측면주사 음탐기 성능향상에 관한 연구

Abstract

Side Scan Sonar is a useful and most widely-used sonar equipment for mapping the ocean bottom bathymetry.

In this thesis, the modeling and signal processing techniques for beam pattern and source signal are developed for designing and improving the performance of Side Scan Sonar. Specifically, the simulation technique to calculate the beam pattern for various arrangement of sensors are presented. Also, the chirp signal is used as a source signal and the performance of chirp signal is discussed. The modeling results are compared to the water tank and sea experiment results. The developed modeling technique can be applied to further improvement of Side Sonar Scan.
