A Review of ISAR Imaging Technology

2020 IEEE International Conference on Information Technology,Big Data and Artificial Intelligence (ICIBA), 2020
With the requirements of radar resolution improving, the aperture of traditional radar has become the bottleneck of its development. In order to overcome this problem, phased array radar and virtual aperture radar are proposed. Virtual Aperture Radar can be divided into Synthetic Aperture Radar (SAR) and Inverse Synthetic Aperture Radar (ISAR).

Complex object's ISAR image simulation

Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005. IGARSS '05., 2005
This paper concerns the Inverse Synthetic aperture radar (ISAR) image of an object over a perfectly conducting ground plane or a lossy dielectric such as sea water. The first step, the “shooting and bouncing rays” (SBR) is used to solve this problem. The next step, the wide signal bandwidths and synthetic aperture are used to resolve objects rotating ...

Pose estimation for ISAR image classification

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
This paper presents aircraft target recognition (ATR) system using Inverse Synthetic Aperture Radar (ISAR) images. Knowing the pose of the target can improve the ATR performance (recognition rate and computational complexity). So, we propose in this paper a new pose estimator from ISAR images, based on the axis of symmetry and the similarity measure ...

Hybrid SAR/ISAR for distributed ISAR imaging of moving targets

2015 IEEE Radar Conference (RadarCon), 2015
The hybrid SAR/ISAR processing takes advantages of both SAR and ISAR to generate high-resolution imagery of moving targets. In this paper, we introduce the concept of hybrid SAR/ISAR, discuss how to reform a high-resolution imagery of moving targets and extract 3-D target feature through hybrid processing of the data taken by multiple arbitrarily ...

Efficient classification of ISAR images

IEEE Transactions on Antennas and Propagation, 2005
In this paper, we propose a method to classify inverse synthetic aperture radar images from different targets. Our approach can provide efficient features for classification by the combined use of a polar mapping procedure and a well-designed classifier. The resulting feature vectors are able to meet the requirements that efficient features should have:

Polar reformatting for ISAR imaging

Proceedings of the 1998 IEEE Radar Conference, RADARCON'98. Challenges in Radar Systems and Solutions (Cat. No.98CH36197), 2002
Polar reformatting is a technique that has been developed and used extensively in spotlight SAR processing. The prerequisite for using this technique is to know the radar's aspect angle, with respect to the target, for each pulse received by this radar.

Target Recognition by Means of Polarimetric ISAR Images

IEEE Transactions on Aerospace and Electronic Systems, 2011
Automatic 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

Motion estimation and compensation in SAR/ISAR imaging

[Proceedings] ICASSP-92: 1992 IEEE International Conference on Acoustics, Speech, and Signal Processing, 1992
The authors present a synthetic aperture radar (SAR) coherent system model and inversion (ISAR) to image a target moving with an unknown constant velocity in a stationary background. It is shown that SAR imaging of a moving target can be converted into imaging the target in a stationary squint-mode SAR problem where the parameters of the squint-mode ...

Simulation of shipborne ISAR imaging

2012 IEEE 11th International Conference on Signal Processing, 2012
Shipborne inverse synthetic aperture radar (ISAR) imaging is in imperious demands with warfare at sea tending to be the key battle field in the future. Simulations of shipborne ISAR imaging are studied when ships are yawing, pitching and rolling are studied.

Optimal sensor positioning for ISAR imaging

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
ISAR imaging is a powerful signal processing that allows obtaining images of non-cooperative targets [1, 2]. Such images are often used as input to classification and recognition systems since they contain useful two-dimensional features [3, 4, 5, 6].
