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

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.

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.

An eigenvector approach for inverse synthetic aperture radar (ISAR) motion compensation and imaging
TENCON '97 Brisbane - Australia. Proceedings of IEEE TENCON '97. IEEE Region 10 Annual Conference. Speech and Image Technologies for Computing and Telecommunications (Cat. No.97CH36162), 2002Inverse synthetic aperture radar (ISAR) is a high resolution imaging radar. The image reconstruction of ISAR involves two steps; motion compensation and image formation. In this paper, an eigenvector approach is proposed to carry out ISAR motion compensation.

Inverse Synthetic Aperture Radar Imaging Using Fourier Transform Technique
2019 1st International Conference on Innovations in Information and Communication Technology (ICIICT), 2019Inverse Synthetic Aperture Radar (ISAR) imaging techniques are used to estimate the target spatial image using target backscatter data. In the ISAR measurement environment, the target is often modeled as a collection of point scatterers to take advantage
