Hybrid polarimetry inverse synthetic aperture radar

open access: yesIET Radar, Sonar & Navigation
The inverse synthetic aperture radar (ISAR) system exploits the movement of the target to form its high‐resolution image. Further, the multi‐polarisation acquisition in ISAR collects additional information on the target's scattering properties and ...

MVFRnet: A Novel High-Accuracy Network for ISAR Air-Target Recognition via Multi-View Fusion

open access: yesRemote Sensing, 2023
Inverse Synthetic Aperture Radar (ISAR) is a promising technique for air target imaging and recognition. However, the traditional monostatic ISAR only can provide partial features of the observed target, which is a challenge for high-accuracy recognition.
