IET Communications, Volume 19, Issue 1, January/December 2025.A virtual array‐based method is proposed to jointly detect communication signals and estimate the starting position and cCFO. It constructs virtual arrays based on the linear phase characteristics of the training sequence regardless of the specific signal structure, which allows it a wide range of applications.

An ISAR target motion estimation algorithm based on a differential semblance criterion
Electronics Letters, Volume 61, Issue 1, January/December 2025.This study presents a novel approach for improving rotational motion estimation in multistatic Inverse Synthetic Aperture Radar (ISAR) imaging through a Differential Semblance Optimization (DSO) criterion. By reducing discrepancies across images from multiple transmitter–receiver pairs, our method enables precise yaw rotation estimation and produces ...

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 ...
