INVERSE SYNTHETIC APERTURE RADAR (ISAR)
, 2001 Imaging of tracked moving targets is possible by applying the principles of synthetic aperture. The relative motion between the target and the fixed radar system creates this aperture. The necessary rotation of the target with respect to the line of sight amounts to only few degrees.

Analysis of jamming on inverse synthetic aperture radar (ISAR)
SPIE Proceedings, 2005 Inverse synthetic aperture radar (ISAR) is a powerful means in target identifying, especially the target in the air, which can image the moving target. There is little study on modeling and resistance technique according to ISAR in China. This paper establishes a model of ISAR system, and then studies on some valid jamming technique.

Data Level Fusion of Multilook Inverse Synthetic Aperture Radar (ISAR) Images
35th IEEE Applied Imagery and Pattern Recognition Workshop (AIPR'06), 2006 Although techniques for resolution enhancement in single-aspect radar imaging have made rapid progress in recent years, it does not necessarily imply that such enhanced images will improve target identification or recognition. However, when multiple looks of the same target from different aspects are obtained, the available knowledge base increases ...

A comparison of some electronic countermeasures on Inverse Synthetic Aperture Radar (ISAR)
Journal of Electronics (China), 2006 Inverse Synthetic Aperture Radar (ISAR) is an important means for target classification, recognition, identification and many other military applications. A simulation model of ISAR system is established after analyzing the principle of ISAR imaging, and then several ECM (Electronic Counter Measurement) techniques are studied.

Autofocus for inverse synthetic aperture radar (ISAR) imaging by beamforming
Proceedings of the 1998 IEEE Radar Conference, RADARCON'98. Challenges in Radar Systems and Solutions (Cat. No.98CH36197), 2002 Autofocus is critical for inverse synthetic aperture radar (ISAR) imaging. This paper develops two new approaches of autofocus for ISAR imaging based on beamforming. The ISAR observation model is established and the proposed approaches are described in detail.

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.

SPIE Proceedings, 1995 The U.S. Navy has been interested in applying neural network processing architectures to automatically determine the naval class of ships from an inverse synthetic aperture radar (ISAR) on-board an airborne surveillance platform. Currently an operator identifies the target based on an ISAR display.
