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.

Optimal Sensor Positioning for Inverse Synthetic Aperture Radar
IEEE Transactions on Aerospace and Electronic Systems, 2013Noncooperative target recognition (NCTR) is often based on the use of inverse synthetic aperture radar (ISAR) images. Although ISAR systems are also able to provide an image of the target when the target's motions are not known a priori, the interpretation of the obtained image is not straightforward, and therefore, the target recognition becomes less ...

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 ...

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.
