Interferometric three-dimensional imaging on ground moving target

In this paper, a system of a three-dimensional (3D) interferometric SAR imaging for ground moving targets is analyzed. By using the estimation of angular motion parameters in the cross-range directions, the registration of the respective complex images can be achieved via compensating the respective echoes in the raw data level, and the 3D image can be reconstructed sequentially. Finally, the cross-range resolution of 3D image is analyzed.
