3D RAY TRACING METHOD IN A DYNAMIC MICROWAVE ENVIRONMENT, CAPABLE OF IMPROVING ANALYSIS SPEED THROUGH EFFICIENT ANALYSIS

摘要

PURPOSE: A 3D ray tracing method in a dynamic microwave environment is provided to predict a microwave environment while moving a transmitting point and a receiving point.;CONSTITUTION: An initial position of a transmitting point and an initial position of a receiving point are set after preprocessing(S110,S120). At least a part among microwave disturbing object surfaces located in a visible area is defined by an effective microwave disturbing object surface from the transmitting point(S130). At least a part among patches located in a visible area is defined by an effective patch from the receiving point(S140). A tree is generated using effective patches of the visible area and patches except the visible area(S150). A tree including a visible area and a non visible area is generated by referring to a preprocessing database. A ray is traced(S160).;COPYRIGHT KIPO 2010
