Multi-Target ISAR Imaging of UAV Swarms Using Fast Reweighted Atomic Norm Denoising
Inverse Synthetic Aperture Radar (ISAR) imaging of UAV swarms presents significant challenges due to the coherent superposition of backscattered signals from multiple closely spaced targets. This work explores the extension of the Fast Reweighted Atomic Norm Denoising (FRAND) alg…
