Abstract

This paper proposed the M&S(Modeling & Simulation) method of channel characterization of satellite communication in the operating area of satellite OTM(On-The-Move) terminal. In M&S, received signal profile was acquired by HTZ warfare software which uses 3 dimensional map including building, road information and geographical features, and then was analyzed statistically. And a received signal profile and its statistics from M&S data were compared with those from measured data. The research showed that the simulated received signal profile matched the measured one about 74.8 percent and simulated statistics matched well as roadside trees were excluded.

본 논문은 OTM(On-The-Move: 이동형) 위성단말을 위해 통신 지역에서 지형/지물에 의해 발생될 수 있는 위성신호의 음영 지역을 분석하는 방법을 제시하였다. 지형/지물 정보를 포함하는 3D map을 HTZ warfare M&S(Modeling & Simulation) 도구를 이용하여 수신 신호의 프로파일을 얻고, 이를 Markov 모델을 이용하여 통계적으로 분석하였다. M&S 데이터의 분석 결과는 대전 도심을 실 주행시험을 통해 확보한 수신 프로파일과 비교하였다. 비교 분석 결과, 수신 프로파일은 약 74.8%의 일치를 보였으며, 가로수 영향 배제시 수신 프로파일의 통계적 분석 결과 또한 유사함을 보였다.
