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

Measurements and analysis of the radar cross section of chaff dipoles
IET Radar, Sonar &Navigation, Volume 18, Issue 11, Page 2182-2188, November 2024.Photo of a filament under test in a stereo‐foam support. Abstract A free space test method to measure the Radar Cross Section (RCS) of single dipole elements is presented. The method is such that dipoles can be measured over a large range of frequencies, in free space and without the need of an anechoic chamber.

SA-ISAR imaging algorithm based on the gradient signal recovery method
The Journal of Engineering, 2019 As the radar system tends to be complex, obtaining well-focused images with discontinued apertures becomes a challenge. Here, a new sparse aperture inverse synthetic aperture radar (SA-ISAR) imaging approach through the signal recovery method is proposed.

Performance Analysis on ISAR Imaging of Space Targets
Leida xuebao, 2017 Usually, in traditional Inverse Synthetic Aperture Radar (ISAR) systems design and mode selection for space satellite targets, coherent integration gain in azimuth direction hardly can be analyzed, which depends on target’s motion.
