The pseudoregistration approach to moving target Identification (MTI) is discussed. Even though techniques based on linear interpolation have proven to be adequate for present generation sensors, higher order interpolation will be needed for future sensors. A higher order polynomial interpolation approach is discussed and shown to be robust in the face of random noise as long as data windows of sufficient length are used. A problem of data "extrapolation" which has been encountered in its implementation is illustrated along with the current solution of "frame exclusion." This problem is caused by the displacement of the current image frame being different than the displacements of image frames used for the interpolation.
