Description
In the past a method was presented, that allows to separate frequency components of a moving source. In the wavenumber frequency domain the Doppler shift leads to a rotation of the axis, as long as direction and velocity of the moving source are constant. Originally, a microphone array with 8x8 microphones was used. This leads to a Fourier transformation with eight bins in the direction of movement. By far not enough to estimate the spectrum with narrowband singularities. A new approach shall use a one directional array with 1024 bins or even more. The results of the new approach are presented.
