The inverse problem of solving for impact force history using experimentally measured structural responses tends to be ill conditioned. A computationally efficient deconvolution method with similarities to Fourier analysis and wavelet analysis is introduced. Force reconstructions obtained using measured acceleration responses from beam and plate models are used to verify the method.
