摘要： A method for determining the location of a transmitter (respectively a receiver) in a space defined by one or more reflective surfaces, including the steps of sending a signal from the transmitter (respectively from a set of transmitters); receiving by a set of receivers (respectively by a receiver) the transmitted signal and echoes of the transmitted signal reflected by the reflective surfaces; finding by a first computing module the location of the virtual sources (respectively virtual receivers) of the echoes; mirroring by a second computing module the virtual sources (respectively virtual receivers) into the space and obtained mirrored virtual sources (respectively mirrored virtual receivers); combining by a third computing module the mirrored virtual sources (respectively mirrored virtual receivers) so as to obtain location of the transmitter (respectively the receiver). This method makes use of echoes for localizing the source (respectively receiver) when there is no line of sight between the transmitter(s) and the receiver(s).
