Abstract: 서해에서 천안함 침몰로 인하여 함정에 대한 새로운 방어체계가 시급하게 필요한 상태이다. 특히 서해처럼 수심이 낮고 조류가  급격하게 변화하는 바다에서는 기존  소나 만을 이용하여 방어하는 것으로는 매우 미흡하다.  심해를 포함하여 모든 바다에 적용되는 초음파를 감지하여 잠수함을 감지하는 SOSUS가 있으나 쌍끌이 어선 조업이 행해지고 있고 태풍의 영향을 받는 천해이며, 수온차가 큰  서해에는 부적합하다.  따라서 서해 바다와 같이 낮은 바다에서 잠수함 침투를 조기에 감지하는 새로운 수단이 개발되어야 한다.  
따라서 본 발명에서는 첫째로 수심이 100M 이내로 낮고, 수온차로 인하여 음영 현상이 있어 수평 방향으로 멀리 떨어진 함정에서 잠수함을 감지하기 어려운 서해 지역에서도 침투하는 잠수함을 조기에 감시할 수 있도록 SONAR를 바다 바닥에 설치하는 방안을 구현하고자 하였으며, 센서는 감시하고자 하는 해역에 일정한 간격으로 설치하고 데이터를 중계 전송할 수 있도록 구현하여 침투하는 잠수함을 인접한 곳에서 조기에 정확하게 감지하여 함정 및 관제센터에 보고할 수 있도록 하였다.  
이와 같이 SONAR 센서를 감시하고자하는 바다 바닥에 분산해서 여러 개 설치하면 SONAR와 잠수함간에 나타날 수 있는 음영 구역 문제를 개선시킬 수 있다.  첫째로 다수의 SONAR를 여러 장소에 여러 개를 분산 배치하였기 때문에 한 SONAR와 잠수함간에 음영 구역이 발생되더라도 다른 SONAR와 잠수함간에는 음영 구역이 발생하지 않을 수 있으며, 둘째로 한 SONAR에서 송출한 신호를 다른 SONAR에서도 수신할 수 있도록 하여 SONAR와 잠수함간에 송수신 루트가 형성되지 않더라도 다른 SONAR에서 수신된 신호를 분석하여 잠수함 감지가 가능하기 때문에 음영 문제를 좀더 개선할 수 있으며, 세째로 SONAR를 감시하고자하는 해역 바닥에 설치하기 때문에 수직 방향으로의 음파 송수신로에는 음영 문제가 거의 해소된다.   
음영 문제 개선 외에도, 근접 거리에서 감지하기 때문에 잠수함 반사 신호가 매우 커서 탐지율이 크게 개선될 수 있다.  즉 감시하고자 하는 해역에 침투하는 잠수함을 조기에 정확하게 감지하는 것이 가능하게 할 수 있다.   
 	본 발명에서는 SONAR를 한 지점에서 신호를 송출하여 반사되는 신호를 수신하여 거리 정보를 얻는 단순 초음파를 이용한 레이더 개념을 넘어서서 SONAR 센서에 타 SONAR에 의한 반사파도 수신하며, 자신의 신호 정보 및 타 센서 노의 데이터도 중계 전송 및 라우팅할 수 있는 기능을 갖도록 하여 함정 및 관제 센터에 대잠수함 탐지 정보를 실시간으로 제공할 수 있도록 하였다.  SONAR들 간에 신호 식별을 위해 펄스파 내에서 주파수가 시간에 따라 정해진 순서에 따라 변화하도록 하는 코드를 부여하고, 이 코드를 다른 SONAR들도 알도록 하여 다른 SONAR 에서 발사하여 도달한 신호 및 그 신호가 반사되어 도달한 신호 정보를 모두 획득할 수 있도록 하여 대잠수함 탐지 확률을 높이도록 하였다.   탐지 확률은 이중성 및 음영 지역에 대한 개선 외에도 송출 펄스에 의한 브라인드 문제로 근접된 물체가 안보이는 현상에 대한 탐지 확률도 개선시킬 수 있다.   
본 발명에서는 또한 제한된 주파수를 가지고 모든 SONAR들이 네트워크를 형성할 수 있도록 SONAR의 사용 주파수 대역을 셀 단위로 배치하고, 출력 세기를 제한하여 주파수를 반복적으로 사용할 수 있게 하였으며, 상기 모든 SONAR 노드들이 필요한 때에 데이터를 전송할 수 있도록 CSMA/CD 방식의 MULTIPLE ACCESS 방법을 적용하여 노드 간 상호 간섭이 없도록 하였다. 
  	또한 감지된 SONAR 정보를 함정 및 관제 센터에 신속하게 전달하기 위하여 육지와 만나는 지점에는 지상 통신을 할 수 있는 RF 송수신 장치를 보유한 허브를 두었다. 지상에서는 함정과 관제 센터에 RF 신호나 유선 네트워크로 신호가 신속하게 전달 될 수 있도록 하였다.   
 따라서 본 발명은 서해와 같이 낮고 수온차가 커서 음영 구역 문제 및 탐지 확률이 낮은 천해에서 SONAR를 분산 설치하고 네트워크화하여 잠수함 침투를 조기에 높은 탐지 확률로 신속 정확하게 감지하여 함정 및 관제 센터에 필요 정보를 보내 줄 수 있어 조기 대응이 가능하며, 안전한 상태에서도 임무 수행이 가능하도록 하는데 크게 도움이 될 것이다.
