Range Doppler and Image Autofocusing for FMCW Inverse Synthetic Aperture Radar
IEEE Transactions on Aerospace and Electronic Systems, 2011Inverse synthetic aperture radar (ISAR) is a well-known technique for obtaining high-resolution radar images. ISAR techniques have been successfully applied in the recent past in combination with pulsed coherent radar. In order to be more appealing to both civilian and military fields, imaging sensors are required to be low cost, low powered, and ...

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 ...

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 ...

Autofocusing of (inverse) synthetic aperture radar for motion compensation
Proceedings of the IEEE 1996 National Aerospace and Electronics Conference NAECON 1996, 2002Ground imaging from an airborne synthetic aperture radar (SAR) and conversely aircraft imaging from a ground based radar (ISAR) require the knowledge of the motion of the antenna relative to the target, with an accuracy of a fraction of the wavelength upon a time span of seconds.

Advances in Bistatic Inverse Synthetic Aperture Radar
, 2009 Bistatic geometries are enabled in scenarios where multiple separated transmitters and receivers are employed as well as when illuminators of opportunity are exploited. Bistatic Inverse Synthetic Aperture Radar (B-ISAR) becomes the radar imaging tool for

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 ...
