Abstract :
The problem of linear interpolation of nonstationary multidimensional processes with stationary increments is studied. The expressions for the interpolation filters and for the estimation error are derived, which generalize the results of the interpolation theory for stationary processes. Both finite and infinite extent interpolation are considered. An application to the interpolation of an underwater depth map is presented
