Photonic signal processing for inverse synthetic aperture radar imaging.
A robust signal processor, capable of handling a multitude of signal processing functions over a wide instantaneous signal bandwidth is needed for future military systems where shared sensor and signal processing resources will be employed. We investigated a novel 2D acousto-optic (AO) processor capable of real-time multifunction signal processing.

Bayesian Inverse Synthetic Aperture Radar Imaging
IEEE Geoscience and Remote Sensing Letters, 2011In this letter, a novel algorithm of inverse synthetic aperture radar (ISAR) imaging based on Bayesian estimation is proposed, wherein the ISAR imaging joint with phase adjustment is mathematically transferred into signal reconstruction via maximum a posteriori estimation.

Bistatic inverse synthetic aperture radar imaging
IEEE International Radar Conference, 2005., 2005The use of a monostatic radar configuration limits the ability of an inverse synthetic aperture radar (ISAR) system to image targets in certain geometries. By employing bistatic geometries this limitation may be overcome. Bistatic radar systems will pay a great role in the coming decade since a large number of radar missions are being foreseen.

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 exploiting dictionary learning
2018 IEEE Radar Conference (RadarConf18), 2018We consider the Inverse synthetic aperture radar (ISAR) imaging with under-sampled data in the framework of compressive sensing (CS) theory. In the existing studies of CS based ISAR imaging or sparse ISAR imaging, the scene to be imaged is simply assumed to be sparse or existing transforms, such as the wavelet transform, etc.

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 ...

Inverse Synthetic Aperture Radar imaging at 580 GHz
2008 33rd International Conference on Infrared, Millimeter and Terahertz Waves, 2008We have demonstrated sub-centimeter resolution inverse synthetic aperture radar (ISAR) imaging using a 580 GHz, frequency modulated continuous wave (FMCW) radar. This ISAR technique uses pulse compression possible with the FMCW waveform to achieve resolution in range, and exploits rotation of the target to achieve resolution in cross-range.
