In this paper, we present experimental results on SAR image co-registration. The simple-coregistration method does not requires information on coordinates of flights, ground scene and so on. Two reference samples in each SAR image that can be easily selected are what the method requires. The method is based on re-sampling SAR images with respect to a selected image plane. The re-sampling was performed based on 2-D fast Fourier transform and cubic spline 2D interpolation. The experimental results in multitemporal data with ICEYE satellite data show an increase in the coherence magnitude between the images after the co-registration method. Namely, the coherence increases about three times after co-registration in a particular setting.
