Construction scheme of transfer matrix, by using a two-dimensional uniform impulse response \(h_{e}(\overline{r})\). Note that \(vect(h_e(\overline{r}{-}\overline{\tau }))\) denotes a vectorization of a two-dimensional impulse response shifted from the origin by \(\overline{\tau }\), where \(\overline{\tau }_1\) and \(\overline{\tau }_2\) are two possibly different shift factors
