Abstract: For the source-localization at moving objects, the 2.5D Boundary element method shall be applied. This is possible in the frequency wavenumber domain in the direction of the movement. The velocity of the object leads to a rotation of the axes in the wavenumber frequency domain. Using the reciprocity theorem leads to a matrix of transfer functions of the velocities at the boundary of the moving object and the measurement positions. This matrix has to be inverted taking the ill-posed character of the matrix into account. The L-curve method and the Tikonov method will be applied.
