Abstract
The present invention relates to a method and apparatus for detecting a signal propagation type. The method comprises: calculating a similarity value of a currently received pulse response and a reference pulse response when a certain positioning base station of a UWB positioning system currently receives a pulse response from a certain positioning tag, the similarity value indicating the degree of similarity between the currently received pulse response and the reference pulse response, wherein the reference pulse response is a pulse response previously received by the positioning base station from the positioning tag; and determining the current type of signal propagation between the positioning base station and the positioning tag on the basis of the similarity value. The method and apparatus can detect the type of signal propagation between the positioning base station and positioning tag of the UWB positioning system.
