High resolution SAR image analysis by new autoregressive algorithm in image space

Classical high resolution (HR) methods become unrealizable when applied to large SAR images, due to memory size and computational time requirements. In this paper, a new HR spectral analysis method, called "image space", derived from autoregressive (AR) spectral analysis, is proposed for large-image SAR processing. Simulations and real data processing results are provided, and demonstrate resolution improvement as well as "good" behavior on clutter.
