ISAR Imaging of Maneuvering Targets Based on the Modified Discrete Polynomial-Phase Transform
Sensors, 2015 Inverse synthetic aperture radar (ISAR) imaging of a maneuvering target is a challenging task in the field of radar signal processing. The azimuth echo can be characterized as a multi-component polynomial phase signal (PPS) after the translational ...

Refocusing Moving Ship Targets in SAR Images Based on Fast Minimum Entropy Phase Compensation
Sensors, 2019 Moving ship targets appear blurred and defocused in synthetic aperture radar (SAR) images due to the translation motion during the coherent processing. Motion compensation is required for refocusing moving ship targets in SAR scenes.

Resolution and Micro-Doppler Effect in Bi-ISAR System (in English)
Leida xuebao, 2013 Compared to the monostatic radar, bistatic radar has many special characteristics because of its spatial complexity. Bistatic Inverse Synthetic Aperture Radar (Bi-ISAR) can be employed as a radar imaging tool for obtaining non-cooperative target images ...

Resolution Analysis of Microwave Radar Coincidence Imaging for Multiple Imaging Points
IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.In this paper, we propose an Eigen Subspace Characterisation method for analysing the azimuth resolution of an MRCI system, particularly in scenarios involving multiple imaging points within a coherent area. The ESC method is implemented by first constructing the eigen subspace from the reference signal matrix of the MRCI system using the Singular ...

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.Moving targets often appear defocused and displaced in SAR imagery, complicating detection and recognition—especially when displaced into cluttered regions, where signal‐to‐background ratio is reduced. This work presents a multistatic SAR framework that extracts moving target signatures and reconstructs focused images, providing new insights into the ...

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.To address the issues in radar automatic target recognition (RATR) based on high‐resolution range profiles (HRRP)—specifically, the inability of closed‐set methods to handle unknown categories and the limitation of conventional open‐set methods that can only reject unknown categories without further subdivision—this paper proposes the MHA–CoST open‐set

Subinteger Range-Bin Alignment Method for ISAR Imaging of Noncooperative Targets
EURASIP Journal on Advances in Signal Processing, 2010 Inverse Synthetic Aperture Radar (ISAR) is a coherent radar technique capable of generating images of noncooperative targets. ISAR may have better performance in adverse meteorological conditions than traditional imaging sensors.
