Abstract
This paper considers super resolution synthetic aperture radar (SAR) image formation via sophisticated parametric spectral estimation algorithms. Parametric spectral estimation methods are devised based on parametric data models and are used to estimate the model parameters. Since SAR images rather than model parameters are often more appreciated in SAR applications, we use the parameter estimates obtained with the parametric methods to simulate data matrices of large dimensions and then use the fast Fourier transform (FFT) methods on them to generate SAR images with super resolution. Experimental examples using the MSTAR and ERIM data illustrate that robust spectral estimation algorithms can generate SAR images of higher resolution that the conventional FFT methods and enhance the dominant target features.
