  • Locating method for localizing at least one object using wave-based signals and locating system
    Patent number: 11555881
    Abstract: The invention relates to a locating method for localizing at least one object using wave-based signals, wherein a wave field emanates from the object to be localized and the wave field emanating from the object is received by a number N of receivers, at least one measurement signal is formed in every receiver, said measurement signal being dependent on the spatial and temporal distribution of the wave field and the phase progression of said measurement signal being characteristically influenced by the signal propagation time from the object to the receiver, wherein, for position locating, phase values for each of the at least two measurement signals are taken as measured phase values, and wherein the current position (P(k)) of the object to be located at the time k is determined by a comparison of at least one linear combination of the measured phase values with at least one linear combination of the associated hypothetical phase values, which result from the transmitter-receiver distance(s), and using a recu
