ANALYSIS METHOD AND DEVICE FOR PROPAGATION CHARACTERISTICS OF ELECTROMAGNETIC WAVE

摘要

The embodiments of the present invention provide an analysis method and device for propagation characteristics of radiation. The method mainly comprises: establishing a virtual source tree including multi-level virtual sources according to pre-stored environmental information and position of an emission source, inquiring the virtual source tree according to the positions of the emission source and a reception point, obtaining the propagation path from the emission source to the reception point, and calculating and combining field intensities of the reception point where electromagnetic wave of each propagation path arrives, thereby obtaining the corresponding field intensity of the reception point. With the embodiments of the present invention, a new virtual source tree including multi-level virtual sources and with a new binary tree structure is established, and a more accurate propagation model can be established according to the virtual source tree, thereby effective analysis of propagation characteristics, such as propagation path, field intensity, of electromagnetic wave can be performed.
