Abstract

In actual urban scenes, the uncanonical facilities complicate the EM wave propagation environment, which makes traditional methods hard to work. To solve this problem, a novel method for Localization based on ray tracing is established. Firstly, the ray tracing technique is introduced to calculate the theoretical propagation path from the target, by which a dictionary of predicted multipath signals relative to different position parameters is constructed. Consequently, the position of the target can be estimated via matching Euclidean distance between the received multipath echoes and the predicted multipath dictionary. The simulation experiments show that the proposed method has higher localization accuracy especially in complicated scene.
