Inverse Synthetic Aperture Radar Imaging: A Historical Perspective and State-of-the-Art Survey
Radar can obtain high spatial resolution at large operating distances, and its operation is largely independent from weather and lighting conditions. This makes it an important instrument in an ever-increasing number of applications requiring robust and ...

Sparse aperture wide-angle inverse synthetic aperture radar imaging based on compressive sensing
In high-resolution inverse synthetic aperture radar (ISAR) imaging, if the authors enlarge observation angle, range migration would appear and that can cause defocus problem.
