Abstract

We describe the SAR Scintillation Simulator (SAR-SS), a new phase screen model for simulating the impact of small-scale ionospheric structure on SAR image formation and interferometry. We compare simulated and observed PALSAR imagery over Brazil, and our preliminary findings show that SAR-SS can reproduce the essential features of azimuthal streaking and contrast degradation caused by small-scale structure in the ionosphere.
