Warp-Based Stabilization for Autofocused Video SAR Sequences

To address the issue of undesirable shaking motion within the viewport of autofocused video SAR sequence, sequence stabilization through registration is required. Under the assumption of translation motion between autofocused video SAR frames, we propose a warp-based stabilization algorithm that incorporates 2D clustering of matching pairs, reference frame update, and re-autofocusing. The algorithm’s performance is assessed using similarity measures, demonstrating its effectiveness in stabilizing video SAR.
