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.

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 ...

The resolution capabilities in inverse synthetic aperture radar
1989The 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.

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.
