Analysis of jamming on inverse synthetic aperture radar (ISAR)
SPIE Proceedings, 2005Inverse 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.

Inverse Synthetic-Aperture Radar(ISAR) Images Recognition Using Deep Learning
2020 Advanced Computing and Communication Technologies for High Performance Applications (ACCTHPA), 2020We propose a method to recognize and classify inverse synthetic-aperture radar (ISAR) images of a target. The information that is combined from various image frames, it is generally in the context of time-averaging to remove statistically atomic noise shifts in the images.

A comparison of some electronic countermeasures on Inverse Synthetic Aperture Radar (ISAR)
Journal of Electronics, 2006Inverse 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.

Inverse synthetic aperture radar (ISAR)
2001Imaging 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.

Data Visualization for Low-Frequency Inverse Synthetic Aperture Radar (ISAR)
International Journal of Interdisciplinary Telecommunications and Networking, 2018The purpose of this article was to use ISAR to determine the distance between the receiving antenna and the transmitting antenna. Once a systematic approach has been determined, this article could be used on a spacecraft to locate debris in the path of the carrier.

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), 2002Autofocus 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.

The use of entropy to focus inverse synthetic aperture radar (ISAR) images
Proceedings Electronic Technology Directions to the Year 2000, 2002Inverse 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.

Data Level Fusion of Multilook Inverse Synthetic Aperture Radar (ISAR) Images
35th IEEE Applied Imagery and Pattern Recognition Workshop (AIPR'06), 2006Although 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 ...

Distortion in the ISAR (inverse synthetic aperture radar) images from moving targets
2004 International Conference on Image Processing, 2004. ICIP '04., 2005A physics-based numerical model has been developed to model the formation of severe distortion that is observed in ISAR images from moving targets. When a target possesses a small time-varying perturbed motion, a modulation effect is introduced in the phase of the radar return from the target. As a result, a broad smearing appears in the cross-range of
