Relativistic Effects in Bistatic SAR Processing and System Synchronization [PDF]
, 2012 This paper addresses relativistic effects in bistatic and multistatic SAR systems and missions. It is shown that the use of different reference frames for bistatic SAR processing and bistatic radar synchronization is prone to nota-ble phase and time ...

An LFM-Based Semiblind Synchronization Method for Bistatic Radar Imaging
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingBistatic radar provides an additional degree of freedom in the observing geometry for imaging by using a spatially separated transmitter and receiver. This capability allows the capture of scattering phenomena at various bistatic sensing angles, which ...

Assessing GNSS Reflectometry for High‐Latitude 3D Ionospheric Imaging
Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract This study investigates whether Global Navigation Satellite System Reflectometry (GNSS‐R) measurements from low‐Earth‐orbit (LEO) satellites can improve three‐dimensional (3D) ionospheric electron density imaging, with a focus on high‐latitude regions. Conventional ionospheric tomography is limited by sparse ground‐based receiver coverage over

Space‐Time‐Coding Metasurfaces Enabling Programmable Range‐Angle‐Dependent Energy Auto‐Scanning
Nanophotonics, Volume 15, Issue 14, 27 July 2026.This paper presents a novel energy auto‐scanning system based on a space‐time‐coding metasurface. By applying progressive time‐delayed, time‐varying phase modulation, the system generates non‐uniform, temporally evolving electromagnetic field distributions across both angle and range.

Target Coordinates Estimation by Passive Radar with a Single non-Cooperative Transmitter and a Single Receiver [PDF]
Journal of Communications Software and Systems, 2020 Passive radar is a bistatic radar that detects and tracks targets by processing reflections from non-cooperative transmitters. Due to the bistatic geometry for this radar, a target can be localized in Cartesian coordinates by using one of the following ...
