초록

본 논문에서는 해상풍력발전기와 해상감시 레이더 간 다중 반사 경로에 의해 발생할 수 있는 레이더 허위 표적 발생 가능성을 분석하였다. 본 연구에서 설정한 레이더 및 풍력발전기 특성을 반영하여 분석한 결과, 레이더와 풍력발전기가 약 4 km 이상 떨어지면 다중 반사 경로에 의한 허위 표적 발생 가능성이 낮아진다. 다만, 실제 해상풍력 발전단지가 추진될 때는 인근 레이더와 풍력발전기의 특성을 반영한 분석 결과에 따라 레이더와 해상풍력 발전단지 간 최소 이격 거리를 설정하는 것이 타당하다.

Abstract

This paper evaluates the potential for false radar targets caused by multipath reflections between offshore wind turbines and maritime surveillance radars. Simulation results, based on specific radar and turbine parameters, demonstrate that the probability of false targets decreases significantly at distances exceeding 4 km. Nevertheless, establishing a minimum separation distance for actual wind farm deployments requires a case-specific analysis that incorporates the distinct technical characteristics of the local radar and turbine systems.
