강정항 VTS 시스템 구축시 음영구역 최소화를 위한 레이더의 위치 설정에 관한 연구

Abstract

We have studied the efficient operation of the radar and the appropriateness of the installation location, when constructing the VTS system. As the Civil-Military Complex Harbour(Kangjeong port) is completed in 2016, we set the control area within 10 nautical miles centering on Kangjeong Port, and found out and removed the operational radar blind area of VTS system, to provide safe navigation information for vessels that navigating this area. Assuming that two international cruise ships entering at the same time, we performed the radar simulation and compared the images by considering the three sites of Kangjeong Port, Miaksan and Seoguipo Port. Simulation results for a single radar installed at Kangjung Port indicate that the blind area was largely affected by two large cruise ships and the surrounding islands. The blind area due to Kogunsan was considerably large when installed in Miaksan and the blind area due to the influences of Beomseom, Moonseom and Seopseom was also negligibly large. It seems that additional radar installation is necessary as a complementary solution to solve this blind area. Therefore, when two radars were installed at Miaksan and Kangjeong Port, the residual blind area due to the Seopseom was 0.25 km2, and it was at 0.1~0.33 nautical miles in the southeast direction from Seopseom. In addition, the remaining blind area with two cruise ships mutually influenced was 0.18 km2, which did not occur when the cruise ship was only one.
