Method for the analysis of a wave field in relation to at least one propagation direction wherein from at least one emission-device arrangement of an emitter, m signa sequences which are de-correlated against each other with A signals respectively having a known phase relation to each other, are emitted via s different emission devices (a1, a2) and/or different places and/or orientations of the emission-device arrangement, wherein s is greater than or equal to two, wherein A is greater than or equal to two and wherein m is greater than or equal to two, and wherein at at least one receiver reception is made, wherein an emission characteristic of the emission-device arrangement in the form of a set of complex matrices is used indicating a representation which shows which signals can be received at the receiver, when known signals are being emitted, and the representation being dependent of the propagation direction of the signals in order to determine the propagation direction of the signals to the receiver as seen relatively from the emitter, characterized by the determination of the propagation direction being done by way of at least one distance calculation between the set of complex matrices of the emission characteristic and an auto-correlation matrix AKM and characterized by determination of at least one matrix out of the set of complex matrices of the emission-characteristic with the minimum distance to the auto-correlation matrix, the distance calculation being performed by way of a projection between the Eigenvector space or the Eigen-vector sub space of the auto-correlation matrix and the emission characteristic, whereby the auto-correlation matrix is elaborated or calculated from at least two not fully correlated measuring vectors of at least two of the m signal sequences, which measuring vectors were taken at the receiver, wherein said measuring vectors respectively are formed by measurements of at least two of the A signals of one of the m signal sequences, and characterized by the propagation direction being determined from the at least one matrix of the set of complex matrices of the emission-characteristic with the minimum distance, based on each matrix in the set of the complex matrices of the emission-characteristic being allocated to a propagation direction. wherein s is greater than or equal to two, wherein A is greater than or equal to two and wherein m is greater than or equal to two, and wherein at at least one receiver reception is made, wherein an emission characteristic of the emission-device arrangement in the form of a set of complex matrices is used indicating a representation which shows which signals can be received at the receiver, when known signals are being emitted, and the representation being dependent of the propagation direction of the signals in order to determine the propagation direction of the signals to the receiver as seen relatively from the emitter, characterized by the determination of the propagation direction being done by way of at least one distance calculation between the set of complex matrices of the emission characteristic and an auto-correlation matrix AKM and characterized by determination of at least one matrix out of the set of complex matrices of the emission-characteristic with the minimum distance to the auto-correlation matrix, the distance calculation being performed by way of a projection between the Eigenvector space or the Eigen-vector sub space of the auto-correlation matrix and the emission characteristic, whereby the auto-correlation matrix is elaborated or calculated from at least two not fully correlated measuring vectors of at least two of the m signal sequences, which measuring vectors were taken at the receiver, wherein said measuring vectors respectively are formed by measurements of at least two of the A signals of one of the m signal sequences, and characterized by the propagation direction being determined from the at least one matrix of the set of complex matrices of the emission-characteristic with the minimum distance, based on each matrix in the set of the complex matrices of the emission-characteristic being allocated to a propagation direction.
