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.

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.

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.

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

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 ...

Cross-band Inverse Synthetic Aperture Radar (ISAR) Image Fusion
2007 International Symposium on Signals, Systems and Electronics, 2007Research on image fusion is making rapid progress recently, because multiple looks of the same target from different aspects will increase the available knowledge and allow more useful target information to be extracted. Studying on the physical principle of constructing radar images, especially inverse synthetic aperture radar (ISAR) images, make the ...

Novel scheme for inverse synthetic aperture radar (ISAR) imaging data compression
2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559), 2002The characteristics of the inverse synthetic aperture radar (ISAR) imaging data are fully analyzed from the view of complex image compression and the corresponding compressing method, Compression of AMplitude and Phase (CAMP) scheme for the phase history data, is proposed and verified by the real ISAR data.

A new auto-focus algorithm for inverse synthetic aperture radar (ISAR) imaging
Processing Workshop Proceedings, 2004 Sensor Array and Multichannel Signal, 2005Autofocus is imperative for inverse synthetic aperture radar (ISAR) imaging. In this paper an approach for ISAR autofocus is developed by use of second order statistics (SOS) of returned signals. The ISAR observation model is established, the approach is verified and the relationship of the developed approach to other methods is investigated.
