Noise reduction in ISAR imaging of UAVs using weighted atomic norm minimization and 2D-ADMM algorithm [PDF]
arXivThe 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 Ratios (SNRs). It is well-known that the image resolution is affected by the bandwidth of the transmitted signal and the Coherent Processing Interval (CPI) in two dimensions,

, 2020 Inverse Synthetic Aperture Radar (ISAR) is a powerful signal processing technique for imaging moving targets in range and cross-range domains. In this thesis, scattering EM field is collected within a wide band ? wide angle range. If this is the case, FFT method cannot be readily used for 2D ISAR imaging application.

Low-Rank Adaptation of Pre-Trained Stable Diffusion for Rigid-Body Target ISAR Imaging [PDF]
arXivTraditional range-instantaneous Doppler (RID) methods for rigid-body target imaging often suffer from low resolution due to the limitations of time-frequency analysis (TFA). To address this challenge, our primary focus is on obtaining high resolution time-frequency representations (TFRs) from their low resolution counterparts.
