PROBLEM TO BE SOLVED: To provide a method, an apparatus and a system for tracking an electromagnetic wave propagation path.SOLUTION: The method comprises: determining an effective plane of the transmission point on the basis of a predetermined effective plane selection radius; detecting an intersection point of the ray and the effective plane along the direction of the ray for each ray emitted by the transmission point; and when an intersection point of the ray and the effective plane is present and a path cumulative reflection equivalent passing through an effective intersection point of the ray is not more than a predetermined maximum reflection equivalent amount, determining the next path direction of the ray until the ray reaches the receiving area of the receiving point or the path accumulative reflection equivalent passing through the effective intersection of the ray is larger than the predetermined maximum reflection equivalent. According to the embodiment of the present invention, it is possible to reduce the complexity of the calculation process in the path tracking process, to realize more efficient and accurate simulation of the electromagnetic transmission path, and to acquire electromagnetic wave propagation characteristics in the observed wireless network.SELECTED DRAWING: Figure 10 |
