Multi-Target ISAR Imaging of UAV Swarms Using Fast Reweighted Atomic Norm Denoising
Mohammad Roueinfar
Inverse Synthetic Aperture Radar (ISAR) imaging of UAV swarms presents significant challenges due to the coherent superposition of backscattered signals from multiple closely space…
Non-Line-of-Sight imaging using raster scanning at NIR wavelength
Mohammad Roueinfar, Mahdi Salmanian
Non-line-of-sight (NLOS) imaging is an emerging technique with transformative potential, enabling the visualization of hidden objects through indirect light reflection. This paper…
In-Orbit Cosmo-SkyMed antenna pattern estimation by a narrowband sweeper receiver
Mohammad Roueinfar, Masoud Ardini
This paper introduces a novel method for antenna pattern estimation in satellites equipped with Synthetic Aperture Radar (SAR), utilizing a Narrowband Sweeper Receiver (NSR). By ac…
Noise reduction in ISAR imaging of UAVs using weighted atomic norm minimization and 2D-ADMM algorithm
Mohammad Roueinfar, Mohammad Hossein Kahaei
The effect of noise on the Inverse Synthetic Aperture Radar (ISAR) with sparse apertures is a challenging issue for image reconstruction with high resolution at low Signal-to-Noise…
Two-dimensional gridless super-resolution method for ISAR imaging
Mohammad Roueinfar, Mohammad Hossein Kahaei
We are focused on improving the resolution of images of moving targets in Inverse Synthetic Aperture Radar (ISAR) imaging. This could be achieved by recovering the scattering point…
ISAR imaging of space objects using encoded apertures
M. Roueinfar, M. H. Kahaei
A major threat to satellites is space debris with their low mass and high rotational speed. Accordingly, the short observation time of these objects is a major limitation in space…
