Deception Jamming Against ISAR With Coupled Two-Dimensional Compressive Sensing via Sub-Nyquist Sampling

IEEE Access, 2018
Sub-Nyquist sampling is a common means of interfering with inverse synthetic aperture radar (ISAR) imaging, which has been validated for the feasibility of 1-D compressive sensing (CS) ISAR imaging.

Geniş bant - geniş açı ters yapay açıklıklı radar (TYAR) görüntüleme algoritması geliştirilmesi ve nümerik uygulamaları

, 2020
Inverse Synthetic Aperture Radar (ISAR) is a powerful signal processing technique for imaging moving targets in range and cross-range domains. In this thesis, scattering EM field is collected within a wide band ? wide angle range. If this is the case, FFT method cannot be readily used for 2D ISAR imaging application.

ISAR Imaging of a Rotating Asteroid Irradiated by Pulsar’s Electromagnetic Emission

Cybernetics and Information Technologies, 2019
The aim of the present study is imaging of moving objects, asteroids illuminated by continuous coherent wideband pulsar’s signals. As pulsars are located on more than thousands of light years from Earth, objects crossing pulsars’ emission beams are ...
