Inverse Synthetic Aperture Radar Imaging Using Frame Theory

IEEE Transactions on Signal Processing, 2012
Inverse 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.

Compressive Sensing for Inverse Synthetic Aperture Radar Imaging

2017
In 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].

The resolution capabilities in inverse synthetic aperture radar

1989
The 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.

Autofocusing of (inverse) synthetic aperture radar for motion compensation

Proceedings of the IEEE 1996 National Aerospace and Electronics Conference NAECON 1996, 2002
Ground 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.

A new autofocus method for inverse synthetic aperture radar

Science in China Series E: Technological Sciences, 1997
Motion compensation is a key and difficult step in inverse synthetic aperture radar (ISAR) . The calibration of initial phase errors, which is well known as autofocus, requires very high precision, so it determines the quality of the reconstructed image to a great extent.

Microlocal structure of inverse synthetic aperture radar data

Inverse Problems, 2003
The 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 ...

A C-band inverse synthetic aperture radar system

Proceedings of International Radar Conference, 2002
This 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 ...

Range Doppler and Image Autofocusing for FMCW Inverse Synthetic Aperture Radar

IEEE Transactions on Aerospace and Electronic Systems, 2011
Inverse 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, 1987
Inverse 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 ...
