Efficient and accurate approximation of superresolution spectral estimation methods for SAR imaging
Alex W. Batts,
Brian D. Rigling
Abstract:Superresolution methods of spectral estimation have shown much promise for creating high quality SAR images that are devoid of the inherent shortcomings of classical Fourier techniques. However, many modern spectral estimation techniques involve the estimation of a correlation matrix and manipulations thereof, both of which can be prohibitively expensive. While efficient me thods of co mputing th ese sp ectral es timation te chniques have been explored in the literature, for large scenes with high resolution, … Show more
