Abstract :
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
