초록

본 논문에서는 등속 직선 기동하는 수중표적의 CPA 상황에서의 방위각 정보를 이용하여 표적의 CPA 거리와 속도의 비를 추정하는 기법을 제시한다. 선행 연구를 통해 근접센서를 이용한 포락선 CPA 기법으로 이 값을 추정하는 방안이 제시되었으나, 이는 표적과 수신 센서의 거리가 가깝거나 다중경로로 인한 간섭효과가 커질 경우 성능이 떨어지는 문제를 가진다. 이에 이를 극복하는 방안으로 표적 방위각 정보를 이용하는 방위각 CPA 기법을 제시한다.

In this paper, we present a method for estimating the ratio of CPA distance to velocity of underwater target using target bearing information in CPA situation. This ratio can be estimated by previous research which is Envelope CPA using proximity sensor but it has low performance if the target is close to receiver sensor or bigger interference caused by multi-path effects. Therefore we propose a Bearing CPA technique using a target bearing information as a way to overcome.
