Conventional envelope alignment method of ISAR imaging assumes that the target is a rigid body, and therefore, the correlation between one-dimensional range profiles at neighboring time slots gives a larger value compared to correlation between time separated range profiles.

Simulations of ISAR image errors
IEEE Transactions on Instrumentation and Measurement, 1990The authors present concepts and show simulation results for a number of situations where the ISAR (inverse synthetic aperture radar) image is degraded by errors introduced by the signal acquisition and data processing. These errors result in degradation of resolution, false targets in the image, geometric distortion of the image, incorrect values for ...

Statistical CLEAN Technique for ISAR Imaging
IEEE Transactions on Geoscience and Remote Sensing, 2007Inverse synthetic aperture radar (ISAR) images are frequently used in target classification and recognition applications. Some classifiers often require features that can be more easily obtained by extracting scattering centers from ISAR data rather than by reconstructing ISAR images.

Simulation of shipborne ISAR imaging
2012 IEEE 11th International Conference on Signal Processing, 2012Shipborne inverse synthetic aperture radar (ISAR) imaging is in imperious demands with warfare at sea tending to be the key battle field in the future. Simulations of shipborne ISAR imaging are studied when ships are yawing, pitching and rolling are studied.

Rayleigh-based segmentation of ISAR images
Applied Optics, 2023Inverse synthetic aperture radar (ISAR) provides a solution to increase the radar angular resolution by observing a moving target over time. The high-resolution ISAR image should undergo a segmentation step to get the target’s point cloud data, which is then used for classification purposes. Existing segmentation algorithms seek an optimal threshold in

Efficient classification of ISAR images
IEEE Transactions on Antennas and Propagation, 2005In this paper, we propose a method to classify inverse synthetic aperture radar images from different targets. Our approach can provide efficient features for classification by the combined use of a polar mapping procedure and a well-designed classifier. The resulting feature vectors are able to meet the requirements that efficient features should have:

Inverse synthetic aperture radar (ISAR) imaging is typically useful when there is a need to classify, recognize, or identify a moving target of interest. In fact, an ISAR image highlights two-dimensional (2-D) geometric features of a target, which can provide indications of target's type, size, and other salient information.

Polar reformatting for ISAR imaging
Proceedings of the 1998 IEEE Radar Conference, RADARCON'98. Challenges in Radar Systems and Solutions (Cat. No.98CH36197), 2002Polar reformatting is a technique that has been developed and used extensively in spotlight SAR processing. The prerequisite for using this technique is to know the radar's aspect angle, with respect to the target, for each pulse received by this radar.

The aim of this introductory chapter is to cover some fundamental concepts on ISAR and to highlight some characteristics that make these systems unique, especially related to SAR. Although SAR and ISAR share the same underlining concept of forming a synthetic aperture, they are substantially different in the way they process the radar received signal ...

ISAR for concealed objects imaging
SPIE Proceedings, 2015A new promising architecture of microwave personnel screening system is analyzed in this paper with numerical simulations. This architecture is based on the concept of inverse aperture synthesis applied to a naturally moving person. The extent of the synthetic aperture is formed by a stationary vertical linear antenna array and by a length of subject’s
