Source finding in reflection and refraction environment using based on ray tracing method TRM

음선 추적법 기반 TRM을 이용한 반사 및 굴절 환경 속의 소음원 탐색에 대한 연구

The goal is to find the position of the sound source with the TRM at reflections and refractions environment. The Fermat's principle applied to the ray tracing method are expected to follow the acoustic path in order to obtain acoustic distance and transmittance to. Utilizing them in the TRM was confirmed rear reflectance affect on estimated position, resolution and side lobe. And the TRM performance were superior to one of the beam forming techniques.
