Long-Time Observation-Based Multiattitude ISAR Imaging Method for Moving Ships

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Long-time synthetic aperture radar observation facilitates the tracking and identification of moving targets. However, continuous changes in the attitude of a moving target during long-duration observations cause the azimuth signal’s time– ...

Impact and Compensation of Rainfall Propagation Effect on Pol-ISAR Imaging of Parabolic Antenna

Remote Sensing
Orientation is an important parameter to identify the working status of a parabolic antenna. Polarimetric inverse synthetic aperture radar (Pol-ISAR) is an effective approach to sense the parabolic antenna, but the imaging process may be seriously ...

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 ...

GLRT‐based detection of targets composed of distributed scattering centres

IET Radar, Sonar & Navigation
Attributed scattering problems have been found to be helpful in inverse synthetic aperture radar (ISAR) imaging and target recognition problems. In this model, the scattering centres are divided into two categories: localised and distributed.
