초록

본 연구는 해안 감시 공백 최소화를 위한 해안선 정찰 헬기 운용방안을 연구하였다. 공기부양정 등 고속침투수단을 활용한 적의 해안 침투상황을 가정하여, 이를 탐지하는 정찰 헬기의 운용방법을 Barrier Patrol Model(BPM)로 제시하였다. BPM에 대한 수학적 분석 및 시뮬레이션 모델을 제시하였으며, 시뮬레이션 실험은 헬기 1대와 2대 운용으로 구분하여 실시하였다. 특히 헬기 2대 운용 시 최적의 운용방안을 도출하기 위해 다양한 Test Case를 실험하였다. 정찰 구역을 이분화한 경우(Split), 중간지점에서 일부분을 중첩하여 정찰하는 경우(Overlap), 정찰 구역 크기를 3개 형태(Big, Medium, Small)로 구분하여 2개씩 조합(Combination)하는 경우 등이다. 실험결과로, 먼저 선박의 침투정보가 없을 때는 정찰 구역을 이분화한 형태(Split)가, 침투정보가 있을 때는 조합운용(Medium & Small) 방법이 가장 효과적이었다. 또한 중첩(Overlap) 크기별 탐지율은 선박 침투정보가 없을 경우 중첩 크기가 10%일 때, 선박 침투정보가 있을 경우 중첩 크기가 50% 일 때 가장 효과적이었다. 마지막으로 침투정보의 정확도가 높을 때는 조합운용(Small & Small)이, 정확도가 낮을 때는 정찰 구역을 이분화한 형태(Split)가 가장 효과적이었다. 향후 연구 방향은 다수의 정찰 헬기 가용 시 적정 운용 대수 산출, 탐지 여부에 대한 확률적 적용, 구간 정찰이 아닌 구역 정찰시 탐지율 변화분석 등이 될 것이다. 본 연구는 감시해야 할 해안선 전 지역에 대한 정찰 헬기 운용계획 수립에 활용될 수 있을 것이다.

This research found the operational strategies for the coastline patrol helicopters to minimize the coast guard blank. In particular, the Barrier Patrol Model (BPM) was used to find the operational strategies for these coastline patrol helicopters that detect the enemies infiltrating the shore in a high-speed penetrating craft such as an air-boosting boat. The BPM was simulated mathematically using its simulation prototypes. Specifically, the BPM simulation was conducted for one and two coastline patrol helicopter(s). In addition, various test cases were used in the two-helicopter BPM simulations. These test cases were as follows: (i) dividing the patrol area into two patrol areas (split) and patrolling them with two helicopters, respectively, (ii) patrolling these two patrol areas with two helicopters, respectively, under an overlapping patrol by these two helicopters in the adjoining regions of these areas (overlap), and (iii) dividing the patrol area into three types (big, medium, and small) and conducting the patrol with their combinations for the two helicopters (leading to six patrol-area-type combinations). Notably, the BPM simulations showed that the two-helicopter patrol with a patrol-area-type combination of medium and small was the most effective among all the simulations when the infiltration information of the ship was provided. Otherwise, the split method was the most effective. In addition, the infiltration detection rate was the highest under an overlap size of 10 % when the infiltration information of the ship was not provided. On the other hand, the infiltration detection rate was the highest under an overlap size of 50 % when the infiltration information of the ship was provided. Further, the two-helicopter patrol with a patrol-area-type combination of small and small was the most effective among all the simulations when a high-accuracy infiltration-information of the ship was provided. On the other hand, the split method was the most effective among all the simulations when a low-accuracy infiltration-information of the ship was provided. Subsequently, future research on these BPM simulations should include the following: calculation of the appropriate number of coastline patrol helicopters when operating multiple of them, probabilistic detection of infiltration, and the analysis of the changes in the infiltration detection rate under the area patrol compared to the section patrol. In essence, this research can be used to establish the patrol helicopters' operational strategies for the entire coastline.
