ISAR imaging of helicopter

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
Conventional envelope alignment method of ISAR imaging assumes that the target is a rigid body, and therefore, the correlation between one-dimensional range profiles at neighboring time slots gives a larger value compared to correlation between time separated range profiles.

Coherent multistatic ISAR imaging

IET International Conference on Radar Systems (Radar 2012), 2012
This paper presents methods for Coherent Multistatic Radar Imaging for Non Cooperative Target Recognition (NCTR) with a network of radar sensors. Coherent Multistatic Radar Imaging is based on an extension of existing monostatic ISAR algorithms to the multistatic environment.

Simulations of ISAR image errors

IEEE Transactions on Instrumentation and Measurement, 1990
The authors present concepts and show simulation results for a number of situations where the ISAR (inverse synthetic aperture radar) image is degraded by errors introduced by the signal acquisition and data processing. These errors result in degradation of resolution, false targets in the image, geometric distortion of the image, incorrect values for ...

ISAR for concealed objects imaging

SPIE Proceedings, 2015
A new promising architecture of microwave personnel screening system is analyzed in this paper with numerical simulations. This architecture is based on the concept of inverse aperture synthesis applied to a naturally moving person. The extent of the synthetic aperture is formed by a stationary vertical linear antenna array and by a length of subject’s

Statistical CLEAN Technique for ISAR Imaging

IEEE Transactions on Geoscience and Remote Sensing, 2007
Inverse synthetic aperture radar (ISAR) images are frequently used in target classification and recognition applications. Some classifiers often require features that can be more easily obtained by extracting scattering centers from ISAR data rather than by reconstructing ISAR images.

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 ...

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 ...

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 ...

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
