초록

본 논문에서는 수중 위치 추적(Underwater Localization)을 위한 수평거리 추정 방식 중 음선의 각도 변화를 이용하는 방식을 개선하는 Look-up Table(LUT)를 사용하는 방식을 제안하고 기존 방식과의 연산속도 및 수평거리 오차를 비교한다. LUT를 사용하여 추정하는 방식은 수신기의 음파 도달 시간(Time of arrival : ToA)과 깊이에 따른 Sound Speed Profile(SSP)을 이용하여 만들어진 수평 거리-ToA table을 이용한다. 결과적으로, 음선의 각도 변화를 이용하는 방식에 비해 수평거리 추정오차는 다소 증가하게 되지만, 수신된 ToA에 대응되는 수평거리를 사용한다는 점에서 실시간으로 각도 변화를 추정하는 기존방식에 비하여 매우 빠른 처리가 가능하다.

In this paper, we introduce a underwater ranging algorithm with Look-up Table (LUT) by modifying the existing method which is using the changes of angles of accoustic rays with SSP (Sound Speed Profile). We compare the horizontal distance errors and the calculation times. Our new algorithm exploits Time of Arriva l(ToA) - horizontal distance table based on SSP. This algorithm offers faster calculation speed than the previous one with the slight increase of the distance estimation error.
