Multipath effects on ISAR image reconstruction
IEEE Transactions on Aerospace and Electronic Systems, 1998The effects of specular multipath on the reconstruction of high resolution target image provided by an inverse synthetic aperture radar (ISAR) are investigated. First, a model of the received signal that takes into account the reflections produced by the surface of the Earth is defined, Then, the impulse response of the imaging system used to ...

Hybrid SAR/ISAR for distributed ISAR imaging of moving targets
2015 IEEE Radar Conference (RadarCon), 2015The 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 ...

Superresolution techniques and ISAR imaging
Proceedings of the IEEE National Radar Conference, 2003High-resolution optimal estimation techniques are applied to the problem of radar imaging of rotating objects, sometimes referred to as ISAR (inverse synthetic array radar) imaging. Typical digital range-Doppler processing operations are described, utilizing two spectral estimation techniques. Quality ISAR images have been obtained from such processing,

Multistatic 3D ISAR image reconstruction
2015 IEEE Radar Conference (RadarCon), 2015InISAR imaging has proven an effective tool to produce 3D target reconstruction. 3D target reconstruction solves the problems related to the ISAR image interpretation, due to the unknown target's projection onto the image projection plane. Nevertheless, problems related to shadowing are not solved as scatterers that are not visible cannot be detected ...

Optimal sensor positioning for ISAR imaging [PDF]
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].

3D Tower-Turntable ISAR Imaging
2007 European Radar Conference, 2007This paper studies the effects of peculiarities of an experimental stepped-frequency measurement system in a tower-turntable setup on three-dimensional inverse synthetic aperture radar imaging by simulation of ideal point scatterers. Particular a phase drift, an offset of the elevation rotation center and near range distortion have to be compensated ...

ISAR Imaging with LFM waveforms
2007 1st Asian and Pacific Conference on Synthetic Aperture Radar, 2007This thesis demonstrates a technique involving Linear Frequency Modulation (LFM) waveform and Inverse Synthetic Aperture Radar (ISAR) processing to develop two-dimensional radar images of a missile target. The processing is combination of two high-resolution processes: development of a high-range resolution (HRR) profile in down range using LFM ...
