SAR imaging exploiting multi-path

We present a new filtered-backprojection (FBP) type image reconstruction method for synthetic aperture radar (SAR) that exploits multi-path in the presence of a perfectly reflecting wall. The new method is designed to take advantage of multiple scattering and incorporates the multiple scattered waves in the image reconstruction process enhancing the reconstructed image. We present numerical simulation to demonstrate the performance of the new method. While the focus of this paper is on radar applications, our image formation method is also applicable to other problems arising in fields such as acoustic, geophysical and medical imaging.
