GLRT‐based detection of targets composed of distributed scattering centres

IET Radar, Sonar & Navigation
Attributed scattering problems have been found to be helpful in inverse synthetic aperture radar (ISAR) imaging and target recognition problems. In this model, the scattering centres are divided into two categories: localised and distributed.

Battle damage assessment using inverse synthetic aperture radar (ISAR)

, 2004
An imaging radar, like ISAR, offers a combatant the capability to perform long range surveillance with high quality imagery for positive target identification. Extending this attractive feature to the battle damage assessment problem (BDA) gives the operator instant viewing of the target's behavior when it is hit.

A bistatic inverse synthetic aperture radar sparse aperture high‐resolution imaging algorithm with migration compensation

IET Radar, Sonar & Navigation, 2022
In recent years, bistatic inverse synthetic aperture radar (Bi‐ISAR) imaging of targets with sparse aperture has attracted more and more attention. One of the critical issues is that the Bi‐ISAR imaging of some large targets with rotational motions is ...

Synthesis of Inverse Synthetic Aperture Radar (ISAR) Using Matlab

, 2021
High-resolution radar images can be achieved by employing synthetic aperture radar (SAR) or inverse synthetic aperture radar (ISAR) techniques. It can be shown that SAR and ISAR have the same underlying theory but different configuration. Here the specific problem of aircraft ISAR imaging using ground-based radar is Addressed.
