Paper Abstract

We consider a mono-static synthetic aperture radar (SAR) system ying over a scene of interest, making multiple visits. During each visit, antenna is traversing a dierent arbitrary, but known trajectory. Therefore, the dierence in the positions of the antennas, which we refer to as the baseline vector, is arbitrary and changes at each visit. Our objective is to estimate the displacement in the ground topography and reconstruct the scene radiance. We perform a spatio-temporal correlation of the received signals measured by each antenna. This results in a novel model that relates the correlated signal to the displacement. Next, we estimate the displacement in the ground topography and reconstruct the radiance of the scene by using a ltered-backprojection (FBP) - type method combined with an entropy minimization technique. Finally, we present numerical experiments to demonstrate the performance of the proposed method.
