Inverse synthetic aperture 3-D imaging laser radar
2010 2nd International Conference on Signal Processing Systems, 2010Three-dimensional (3-D) Image can represent target's physical characteristic well and improve target recognition capability, however, conventional optical imaging radar which is limited by the array units or scan system cannot realize the high resolution imaging for moving targets.

Inverse Synthetic Aperture Radar Imaging Using Frame Theory
IEEE Transactions on Signal Processing, 2012Inverse synthetic aperture radar (ISAR) imaging is conventionally addressed by means of fast Fourier transform (FFT) method. In this paper, a frame processing method derived based on frame theory for ISAR imaging is proposed as an alternative to FFT based approaches.

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 ...

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 ...

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 ...

Three-dimensional inverse synthetic aperture radar
2019This chapter introduces the development of a method for 3D reconstruction of moving targets. This method is based on the use of a dual interferometric ISAR (InISAR) system. The interferometric phases measured from two orthogonal baselines are used to jointly estimate the target's effective rotation vector and the heights of the scattering centres with ...

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 ...
