Persistent feature reconstruction of resident space objects (RSOs) within inverse synthetic aperture radar (ISAR) images

CoRR
With the rapidly growing population of resident space objects (RSOs) in the near-Earth space environment, detailed information about their condition and capabilities is needed to provide Space Domain Awareness (SDA). Space-based sensing will enable inspection of RSOs at shorter ranges, independent of atmospheric effects, and from all aspects.

SA-ISAR imaging algorithm based on the gradient signal recovery method

The Journal of Engineering, 2019
As the radar system tends to be complex, obtaining well-focused images with discontinued apertures becomes a challenge. Here, a new sparse aperture inverse synthetic aperture radar (SA-ISAR) imaging approach through the signal recovery method is proposed.

Performance Analysis on ISAR Imaging of Space Targets

Leida xuebao, 2017
Usually, in traditional Inverse Synthetic Aperture Radar (ISAR) systems design and mode selection for space satellite targets, coherent integration gain in azimuth direction hardly can be analyzed, which depends on target’s motion.

Strategies for Monitoring of Assets in Geosynchronous Orbit (GEO) Using Space-Based Sub-THz Inverse Synthetic Aperture Radar (ISAR)

IEEE Transactions on Radar Systems
This paper is concerned with the investigation and analysis of a new operational and technical capability to assess GEO satellites from space-borne platforms using extremely high-frequency high-frequency radar operating at sub-THz frequencies. The concept of close monitoring and highly detailed imagery of GEO assets from all aspects, including those ...

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 ...
