Sparse Array Configuration Optimization Based on Target Priors in Distributed ISAR Imaging
Electronics Letters, Volume 61, Issue 1, January/December 2025.In this letter, we consider the sparse array configuration optimization problem for distributed inverse synthetic aperture radar (ISAR) imaging of long‐range targets, aiming to suppress the strong grating lobes caused by sparse sampling. Particularly, we propose a distributed ISAR configuration optimization method, which constructs an equivalent ...

Hybrid polarimetry inverse synthetic aperture radar
IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.The CTLR hybrid‐pol ISAR offers an efficient solution for non‐cooperative target applications, striking an optimal balance between conventional single‐pol ISAR and the widely used full‐pol ISAR. This approach is particularly advantageous for compact radar systems, such as those used in drones and small ground‐radar setups, where it could prove to be a ...
