Abstract

The commercialization of ITS(Intelligent Transport System) is in sight including V2V(Vehicle-toVehicle) communication and analysis of related electromagnetic circumstances is essential process in relevant legislation. However analysis including numbers of vehicles have electrically large environment which leads to a lack of computational resources. In this letter, we suggest superposition method which require much less computational resources by subgrouping environment and using post-processing of results. Suggested method approximate original result by superpositioning of analysis which include scatterers near source, observation point. This letter also presented guideline of method and example for comparison with full analysis result.

지능형 교통 시스템(Intelligent Transport System; ITS)의 상용화를 위한 작업이 국내외에서 활발하게 이루어지고 있는 시점인 지금 차량 간 통신 (Vehicle-to-Vehicle; V2V) 환경 해석은 관련 법규 제정에 있어서 필수적인 과정이다. 하지만 전기적으로 대형인 도로상 다수의 차량이라는 해석환경으로 인하여 계산 자원 부족으로 일반적인 수치해석 도구를 이용한 환경의 해석이 불가능한 상황에 대하여 본 논문에서는 해석 환경의 적절한 분리와 결과의 후처리로, 적은 계산 자원을 사용하여 환경 해석을 근사할 수 있는 기법을 제안하였다. 제안된 기법은 전자기원(Electromagnetic field source)과 관측 지점 주변, 그리고 그 선상의 산란체들 중 일부만을 포함하는 해석을 수행한 뒤 결과들을 중첩의 원리를 적용한 벡터합을 통하여 결과를 근사하는 방식을 사용하였다. 본 논문에서는 제안한 기법의 적용범위 및 가이드라인, 일반적인 해석 기법과의 정확도 비교를 위한 예시를 제시하였다.
