METHOD AND DEVICE FOR QUICKLY DETERMINING LOCATION-DEPENDENT PULSE RESPONSES IN SIGNAL TRANSMISSION FROM OR INTO A SPATIAL VOLUME

摘要

The invention relates to a method and to a device for determining the location-dependent pulse responses in signal transmission from a transmitter in a transmission volume to a receiver in a reception volume, wherein either the transmitter or the receiver is a device fixed in a predetermined location and the other is a movable device. The method comprises the following steps: continuously emitting a band-limited signal by means of the transmitter; continuously capturing the signal and recording the signal with time indexing by means of the receiver; moving the movable device during the emission and capturing of the signal along a trajectory within the transmission or reception volume while continuously capturing the location coordinates of the movable device and recording said location coordinates with time indexing; numerically solving a linear system of equations, the unknowns of which system of equations represent the pulse responses at discrete sampling points in the transmission or reception volume associated with the movable device, wherein the distances of the sampling points with respect to location coordinates and time index satisfy the Nyquist criterion for sampling the signal.
