초록

본 논문은 근접센서를 이용하여 수중 표적의 정보를 추정하는 수동소나 신호처리 기법을 제안한다. 이 기법은 수중 센서망을 구성하는 단일 센서에서 수행되며 계층적 신호처리 구조를 가진다. 이를 통해 추정되는 표적 정보는 표적의 속도, 깊이, CPA 상황에서의 거리와 방위각이며 계층적 신호처리 구조를 가짐으로써 신호처리 기법의 정확도를 향상시킬 수 있다. 제안하는 기법의 성능을 검증하기 위해 모의실험을 수행하였고 이를 통해 최대 탐지거리 내에서 최대 20%의 오차를 가짐을 확인하였다. 또한 해상실험을 통해 실제 해상환경에서 신뢰성을 가지는지 확인하였다.

In this paper, we propose the passive sonar signal processing technique for estimating target information using proximity sensor. This algorithm is performed by single sensor which is constituted underwater sensor network and has a hierarchical structure. The estimated parameter is the velocity, the depth, the distance and bearing at CPA situations and we can improve the accuracy of signal processing techniques through having a hierarchical structure. We verify the performance of the proposed method by computer simulation and then we check the result that 20% error can be occurred in maximum detectable range. We also confirm that proposed method has the reliability in the actual sea environment through the sea experiment.
