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 ...

An inverse method for the processing of synthetic aperture radar data
Inverse Problems, 1987An inverse method for the processing of synthetic aperture radar signals is presented. The method is independent of the relative bandwidth of the radar signal and should thus work when, for instance, the frequency of the emitted radiation is of the same order as the bandwidth, i.e. in low frequency, high resolution applications.

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 ...

Cross-range scaling of inverse synthetic aperture radar
Proceedings of National Aerospace and Electronics Conference (NAECON'94), 2002This paper investigates the problem of cross-range scaling of inverse synthetic aperture radar. It is very important to target classification and recognition via ISAR. The cross-range scale of ISAR depends on both radar wavelength and rotating angle of target relative to radar-line-of-sight (RLOS) during the total coherent processing time.

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.

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.

Inverse synthetic aperture radar imaging of maneuvering targets
Optical Engineering, 1998Range Doppler imaging, a basic method used in inverse syn- thetic aperture radar (ISAR), is based on the uniform rotation model of a target. The rotation velocity and axis of a maneuvering aircraft often vary with time. Traditional imaging methods may blur the target image and even render it beyond recognition.

Autofocus algorithm of inverse synthetic aperture radar using entropy [PDF]
Inverse synthetic aperture radar is an imaging radar in which the radio image is derived by utilizing the Doppler effect produced by change of the target aspect. When the target is accelerated, the resolution in this radar is degraded due to the frequency modulation of the received signal.
