Abstract

Estimation of digital elevation maps from electromagnetic signals received at an interferometric synthetic aperture radar (SAR) requires significant processing. In this framework, a key step is the interferometric registration, which can be mathematically framed as an interpolation procedure. A new interpolation kernel for SAR interferometric registration is presented and discussed in comparison with five classical ones. It is based on the Knab sampling window that has been successfully employed in various electromagnetic problems and which has been proposed as capable of best preserving the stochastic information. The numerical experiments show the superiority of the new interpolation kernel.
