Near-Space Microwave Radar Remote Sensing: Potentials and Challenge Analysis
Remote Sensing, 2010 Near-space, defined as the region between 20 km and 100 km, offers many new capabilities that are not accessible to low earth orbit (LEO) satellites and airplanes, because it is above storm and not constrained by either the orbital mechanics of ...

Multistatic Synthetic Aperture Radar Autofocus for Back Projection Imaging of a Moving Target
Electronics Letters, Volume 61, Issue 1, January/December 2025.This paper presents a new metric‐based autofocus approach, called Localised Threshold Sharpness (LTS), which employs Multistatic SAR data to localise and focus a target moving with up to six degrees of freedom motion on a real‐time, pulse‐by‐pulse basis.

Ionospheric Faraday Rotation Angle Estimation for Bistatic Spaceborne SAR
Electronics Letters, Volume 61, Issue 1, January/December 2025.This paper proposes a Faraday rotation angle estimation method for bistatic spaceborne SAR. The effectiveness of the method is verified through simulation experiments and the performance of the method is analysed. Under different SNR and filtering window sizes, the estimation error range is 0.02°–0.26°. ABSTRACT Bistatic synthetic aperture radar (SAR)

Beam Footprint Detection and Tracking for Non-cooperative Bistatic SAR [PDF]
Radioengineering, 2016 In non-cooperative bistatic synthetic aperture radar (SAR), the position of transmitter’s beam footprint should be detected and tracked in real-time to perform beam synchronization.

Generalized PFA for Air-Missile Borne Bistatic Forward-Looking Beam-Steering SAR With Accelerations
IEEE Access, 2018 For air-missile borne bistatic forward-looking beam-steering synthetic aperture radar (BFLBS-SAR), the receiver platform moves along a curve track due to the existence of accelerations.

Electronics Letters, Volume 61, Issue 1, January/December 2025.A novel dual‐channel context‐guided feature‐alignment network (CGFAN) that is capable of fusing the cross‐modality projective‐invariant features extracted from unpaired SAR and IR images is proposed. First, region of interest matching between SAR and IR images are realized based on special landmarks exhibiting consistent cross‐modality features.

IGWO‐Based Single Snapshot Error Correction for Motion Array in DOA Estimation
Electronics Letters, Volume 61, Issue 1, January/December 2025.This paper proposes a motion‐based synthetic array framework with error correction tailored for unmanned aerial vehicle (UAV) platforms, along with a multidimensional error calibration method. Experimental results demonstrate that the proposed approach enhances the array aperture (AA) and degrees of freedom (DOF), while enabling highly accurate and ...

Ultra Wideband Low‐RCS Linear Polarised Array Based on Composite Metasurface
IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.The paper proposes a composite metasurface antenna. It significantly enhances the RCS reduction bandwidth compared to a single metasurface, while maintaining the antenna's radiation performance. ABSTRACT This paper proposed the design of an ultra‐wideband antenna array with low radar cross section (RCS) based on a composite metasurface.
