Dynamic Cell Division for Interference Management in Satellite Direct‐to‐Cell Systems
International Journal of Satellite Communications and Networking, Volume 44, Issue 6, Page 757-765, November/December 2026.ABSTRACT Direct‐to‐cell (D2C) connectivity enables future non‐terrestrial networks to provide service directly to standard terrestrial user equipment (UE) when terrestrial networks (TN) are unavailable. In this work, the satellite system is considered as a secondary network that supplements existing TN coverage while minimizing interference to the ...

Experimental Study of the Stability of a Low-Cost C-Band Active Reflector Using Sentinel-1 Imagery
IEEE AccessThe application of Synthetic Aperture Radar (SAR) interferometry (InSAR) techniques when in the imaged areas the coherence is low and persistent scatterers are missing often demands the installation of artificial reflectors, usually represented by ...

Accurate Transponder Calibrations with the Novel Three-Transponder Method [PDF]
, 2015 Transponders are, besides trihedral corner reflectors, the most commonly used measurement standards in radiometric SAR calibration. They allow signal recording for the reconstruction of the azimuth pattern of the SAR system, adjustments of the backscattering matrix for polarimetric applications, and radar cross sections (RCSs) which are potentially ...
