A time domain algorithm for the computation of the maximum likelihood estimate of the location of a known scattering object from wide-band scattering data obtained in a suite of scattering experiments is proposed. It consists of a three-step procedure that includes data filtering, time-domain backpropagation and coherent summation. Results confirm that the log likelihood function for estimation of the location of a known scattering object from noisy wideband scattering data can be calculated through a time-domain, filtered backpropagation algorithm.
