Algoritthms For The Implementation Of STOLT Interpolation In SAR Processing

Abstract

In this paper the shift variant problem in SAR processing will be described. It is shown how the stolt interpolation is carried out. The implementation of Lagrange’s interpolation and samplin interpolation is presented and analysed. The feasibility o f the algorithms for the SAR application is discussed. The Stolt interpolated data will be demonstrated and compared. Finally the problem of extrapolation in SAR si nal processing is explained and discussed. An algorithm wkch implements the extrapolation is presented.
