A Semi‐Analytical Gaussian Beam Summation Method to Compute the RCS of Dielectric and Dielectric‐Coated Targets in Mono or Bi‐Static Configurations

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
In this article, we provide a Gaussian beam‐based method to compute the RCS of dielectric and dielectric‐coated targets in both the monostatic and bistatic cases. ABSTRACT This study proposes to extend and refine the methodology of Gaussian beam summation (GBS) for computing the radar cross section (RCS) of dielectric targets in both monostatic and ...

Mixed Compressive Sensing Back-Projection for SAR Focusing on Geocoded Grid

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
This article presents a new scheme called 2-D mixed compressive sensing back-projection (CS-BP-2D), for synthetic aperture radar (SAR) imaging on a geocoded grid, in a single measurement vector frame.

Dynamic Multistatic Synthetic Aperture Radar Imaging: Resolving Motion via Differential Semblance and k‐Space Diversity

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 ...

Synthetic Bistatic ISAR Imaging for Moving Targets With Prescribed Trajectories and Scattering Regimes: Validation With Passive Radar Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The design of a bistatic inverse synthetic aperture radar (ISAR) images simulator is described, as a response to the need of databases with classification purposes in bistatic radar scenarios characterized by numerous degrees of freedom.

Characterisation and Classification of Resident Space Objects Using Radar Networks

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper describes a simulated environment for generating Inverse Synthetic Aperture Radar (ISAR) images and interferometric point clouds using a three‐receiver radar configuration, along with the creation of extensive datasets to train and evaluate deep learning models under varying Signal‐to‐Noise Ratio (SNR) conditions. Findings show that modified

Joint Decoupling Optimization of Frequency Offsets and Array Elements for Frequency Diverse Arrays

International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.
Frequency diverse array (FDA) has a distance‐angle–dependent beam direction map, which has a greater application advantage than phased array. However, due to the distance‐angle coupling and periodicity of its beam direction map, it makes the parameter information of the target obtained through FDA have ambiguous phenomena. Currently, researchers mostly

An Optically Transparent Transmissive Metasurface for User‐Defined Broadband Electromagnetic Illusion Generation

Small Structures, Volume 6, Issue 12, December 2025.
This work presents a transparent transmissive metasurface (TTM), designed using a conditional generative adversarial network to achieve broadband electromagnetic illusions. The proposed TTM ensures high optical transparency while precisely manipulating electromagnetic waves, demonstrating effectiveness in practical applications such as camouflage ...

Multiangle Bistatic SAR Imaging and Fusion Based on BeiDou-2 Navigation Satellite System

Leida xuebao, 2015
Bistatic Synthetic Aperture Radar (BSAR) based on the Global Navigation Service System (GNSSBSAR) uses navigation satellites as radar transmitters, which are low in cost. However, GNSS-BSAR images have poor resolution and low Signal-to-Noise Ratios (SNR).

Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...
