Target Recognition by Means of Polarimetric ISAR Images
IEEE Transactions on Aerospace and Electronic Systems, 2011Automatic target recognition (ATR) is generally the reason why inverse synthetic aperture radar (ISAR) imaging systems are employed. Moreover, the use of fully polarimetric radar systems in radar imaging applications such as SAR and ISAR has enhanced both image quality and classification capabilities. The authors propose a novel technique for ATR using

Interferometric ISAR Imaging of Maneuvering Targets With Arbitrary Three-Antenna Configuration
IEEE Transactions on Geoscience and Remote Sensing, 2020In order to compensate for the shortcomings of inverse synthetic aperture radar (ISAR) imaging in target recognition, a three-dimensional (3-D) interferometric ISAR (InISAR) imaging technique is developed.

Sparse Frequency Waveform Optimization for High-Resolution ISAR Imaging
IEEE Transactions on Geoscience and Remote Sensing, 2020The stepped-frequency waveform is usually used to synthesize a wideband signal in the radar imaging system. To reduce the amount of data and coherent pulse intervals (CPIs), as well as to improve antijamming abilities, the sparse stepped frequency is ...

SAR, ISAR and hybrid SAR/ISAR-a unified treatment of radar imaging
The Record of the 1993 IEEE National Radar Conference, 2002The modeling of aperture synthesis as a process of Fourier transformation and inversion provides a unified description of synthetic aperture radar (SAR), inverse SAR (ISAR) and hybrid SAR/ISAR techniques. The degradation of the resulting imagery arising from errors in the estimation of target and platform motions and operation in the near field is ...

In the high-resolution inverse synthetic aperture radar (ISAR) imaging of low-earth-orbit space targets, the received signal from one range bin can be modeled as a multicomponent cubic phase signal (CPS) after motion compensation. The chirp rates and the

Recently, high-resolution inverse synthetic aperture radar (ISAR) imaging with sparse aperture (SA) data has attracted increasing attention. The theory of compressive sensing (CS) suggests that an unknown sparse signal can be accurately recovered by taking advantage of very limited samples.

ISAR echoes coherent processing and imaging
2004 IEEE Aerospace Conference Proceedings (IEEE Cat. No.04TH8720), 2004The general approach to ISAR imaging is range-Doppler (RD) imaging approach. For this approach, the translational motion compensation (TMC) is firstly obtained by envelope alignment and autofocus, so the target can be treated as a rotating target for the next processing.

Basic Principles of ISAR Imaging
2014Inverse synthetic aperture radar (ISAR) is different from synthetic aperture radar (SAR) because the former has a larger antenna aperture based on target motion while the radar remains stationary and generates a high-resolution image of moving targets.

Turntable ISAR Imaging of a Circular Array
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019Turntable inverse synthetic aperture radar (ISAR) has a rich history with many significant connections recognized in antenna theory, Fourier analysis, sampling theory, remote sensing inverse problems, medical tomography, imaging, synthetic apertures, radar signals, range and doppler and signal processing. In fact, most ISAR and synthetic aperture radar

Range alignment methods for ISAR imaging
SPIE Proceedings, 2011ISAR is used to image high resolution images of moving targets. Range Alignment is the key for the formation of ISAR images, therefore many methods has been proposed. In this paper, the performance of maximum correlation method, minimum entropy method and global range alignment method are introduced and analyzed.
