Abstract :
We present a high resolution method for spotlight mode SAR imaging that utilizes pole/residue modeling of projected target reflectivity density function and tomographic reconstruction. Utilization of a matrix pencil method (MPM) allows super resolution to be achieved in range for a single imaging angle. Hence the quality of the image reconstructed is also improved. It is shown that the method is very resistant to noise and can generate images down to very low SNR values.
