Abstract
The present invention relates to a method and apparatus for detecting a signal propagation type, the method comprises: when a positioning base station of an ultra-wideband positioning system currently receives a pulse response from a positioning tag, computing an actual value of a specified feature of the received pulse response at least using the received pulse response; selecting, for the specified feature, a predictive model for predicting an adopted value of the specified feature at a future moment on the basis of an adopted value of the specified feature at a historical moment; using the predictive model selected for the specified feature to acquire an adopted value of the specified feature at a future moment, to serve as a predicted value of the specified feature of the received pulse response; and determining the current type of signal propagation between the positioning base station and positioning tag on the basis of the actual value and predicted value of the specified feature of the received pulse response and the predictive model selected for the specified feature. Using the method and apparatus, it is possible to detect the type of signal propagation between the positi…
