Compressive Sensing for Inverse Synthetic Aperture Radar Imaging
2017In the last few decades, the increasing demand for high-resolution images in applications such as automatic target recognition (ATR) and automatic target classification (ATC) for surveillance and homeland security has attracted the attention of the research community worldwide [35].

Microlocal structure of inverse synthetic aperture radar data
Inverse Problems, 2003The work engaged by the authors was motivated by radar applications. But, although the actual radar systems dwell on electromagnetic waves, and targets cause to interrelate the field components, which gives rise to vector wave equations, the authors consider only one scalar functions \(u(t,x)\) satisfying the equation \[ \Delta u- \{1/c^*(t, x)\}^2 ...

The resolution capabilities in inverse synthetic aperture radar
1989The resolution attainable by an Inverse Synthetic Aperture Radar system is discussed. The image reconstruction method is based on recovering the target reflectivity function by an inverse Fourier transform of the received signal samples collected for different positions of radar and target.

Inversion of Synthetic Aperture Radar. Ocean Image Spectra
[Proceedings] IGARSS '92 International Geoscience and Remote Sensing Symposium, 2005An algorithm that inverts SAR Ocean image spectra into long gravity Ocean wavenumber spectra is implemented and applied to both airborne (CCRS CV-580) and spaceborne (ERS-1) c-band SAR data. The nonlinear iterative algorithm is based on a generalized version of Hasselmann's forward spectral transform that also incorporates the range bunching effect ...

A C-band inverse synthetic aperture radar system
Proceedings of International Radar Conference, 2002This paper is devoted to a C-Band ground-based inverse synthetic aperture radar (C-ISAR) system, which has been developed by the Beijing Institute of Radio Measurement (BIRM). Through off-line processing of the real image data collected from the C-ISAR system, two-dimensional radar imaging of observable airborne targets with 0.5 m /spl times/0.5 m ...

Inverse synthetic aperture radar imaging of satellites
International Journal of Imaging Systems and Technology, 1998We present a scheme for radar imaging of satellites by the inverse synthetic aperture radar technique. We include some general principles in image formation when dealing with microwave-scattering experiments, such as radar observation of a satellite, so that the article is not confined to the radar community.

New approach to inverse synthetic aperture radar imaging
Annual Meeting Optical Society of America, 1987Inverse synthetic aperture radar (ISAR) imaging is an extension of synthetic aperture radar (SAR) imaging to cases where the synthetic aperture is produced by target motion (trajectory), as opposed to radar motion, and hence unknown a priori. In SAR knowledge of the motion is used to produce the image; lack of this knowledge causes the ISAR imaging ...

Experimental results for shadow inverse synthetic aperture radar
IET Conference Publications, 2009Bistatic shadow inverse synthetic aperture (SISAR) offer a number of promising features such as: simple hardware; enhanced target radar cross-section (RCS); a long coherent interval of the diffracted signal; robustness to stealth technology; In spite of a number of theoretical research efforts in the application of SISAR for target imaging, there are ...
