Sparse Aperture Inverse Synthetic Aperture Radar Imaging for Maneuvering Targets With Migration Through Resolution Cells Correction

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Due to the nonstationarity of the echo, it is hard to form a well-focused sparse aperture inverse synthetic aperture radar (SA-ISAR) image for maneuvering targets by traditional algorithms.

The use of entropy to focus inverse synthetic aperture radar (ISAR) images

Proceedings Electronic Technology Directions to the Year 2000, 2002
Inverse synthetic aperture radar (ISAR) images generated of targets which have a large angle of rotation or non-linear rotational motion are blurred if the rotational motion is not taken into account. If the rotational motion is known, the data can be corrected by resampling from the polar grid on which the data is collected, to a rectangular grid.

Distortion in the inverse synthetic aperture radar (ISAR) images of a target with time-varying perturbed motion

IEE Proceedings - Radar, Sonar and Navigation, 2003
Large distortion in ISAR images of a moving target has been investigated and demonstrated under controlled experiments. The distortion is a result of small time-varying perturbed motion experienced by the target and is attributed to a modulation effect in the phase of the radar return from the target.

Emerging Trends in Radar: 3D Inverse Synthetic Aperture Radar

IEEE Aerospace and Electronic Systems Magazine
Inverse synthetic aperture radar (ISAR) is a technique used to image noncooperative targets, allowing them to be subsequently classified. However, the quality of ISAR imagery and hence the ability to correctly classify a target is dependent on the target
