Deception Jamming Against ISAR With Coupled Two-Dimensional Compressive Sensing via Sub-Nyquist Sampling

IEEE Access, 2018
Sub-Nyquist sampling is a common means of interfering with inverse synthetic aperture radar (ISAR) imaging, which has been validated for the feasibility of 1-D compressive sensing (CS) ISAR imaging.

Far-field radar cross section determination using near-field ISAR imaging techniques

, 2022
4 S.Inverse synthetic aperture radar (ISAR) imaging is a powerful tool for the characterization of radar targets. Since the direct determination of the far-field radar cross section (RCS) typically requires expensive arrangements and equipment, short ...

Impact and Compensation of Rainfall Propagation Effect on Pol-ISAR Imaging of Parabolic Antenna

Remote Sensing
Orientation is an important parameter to identify the working status of a parabolic antenna. Polarimetric inverse synthetic aperture radar (Pol-ISAR) is an effective approach to sense the parabolic antenna, but the imaging process may be seriously ...

An improved inverse synthetic aperture radar range alignment method based on maximum contrast

The Journal of Engineering, 2019
Inverse synthetic aperture radar (ISAR) is an important tool for non-cooperative ship imaging, and one key step of ISAR imaging is range alignment. To achieve the range alignment with high precision, efficiency and robustness, an improved ISAR range ...
