A method for determining the multipath components of a propagation channel in a geolocation system or an IR-UWB telecommunications system. The IR-UWB emitter emits a plurality of UWB impulses at a plurality of central frequencies, sequentially or in parallel. The receiver translates the response of the channel to each of these impulses into the baseband, integrates it over a plurality of time intervals in order to provide intensity samples related to successive times of flight. The intensity samples related to the same time of flight and to the various frequencies are combined in order to provide a composite sample at the output of a multiband IR-UWB receiver module. The multipath components are determined from the composite samples exceeding a predetermined threshold value.
