동해 북부해역의 수중음향환경과 효과적인 대잠탐지체계 운용방안

Abstract

The northern part of the East Sea. located in the north of Sub-PolarFront, has lager space and colder sea water than the southern part. Astudy, concerned about the underwater acoustic environment in this area,has rarely conducted because of the lack of observations. Recently, wecould occupy the newly updated observation data, which was able tostudy with intensive analysis. Deep convection, cold eddies, LimanCurrent (LC), and North Korea Cold Current (NKCC), joining with LC andflowing along east coast of the Korea, make more complicate andunpredictable underwater acoustic environment and results of the analysisprovide a severe inconsistency for that of the south. It will force R. O. KNavy to consider much restriction and difficulty in this area wheneverwe will conduct the Anti-Submarine Warfare (ASW). This study suggestseffective operating method of high frequency active sonar based ASWdetection system under possible ASW situation in a case of emergency.
