An Unbalanced Sinuous Antenna for Near-Surface Polarimetric Ground-Penetrating Radar

IEEE Open Journal of Antennas and Propagation, 2020
Sinuous antennas are capable of producing ultra-wideband radiation with polarization diversity. This capability makes the sinuous antenna an attractive candidate for UWB polarimetric radar applications. Additionally, the ability of the sinuous antenna to

Digital beam forming methods for variable polarimetric monopulse radar

IET Radar, Sonar & Navigation, 2021
In variable polarimetric monopulse radars, due to the number and types of data channels, the polarisation and angle information of the target in the receiving signals are non‐linearly coupled, which results in incorrect polarisation measurement and ...

Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade

Radio Science, Volume 60, Issue 7, July 2025.
Abstract The Deep Space Network (DSN) has been a core operational element of NASA's crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique ...

Potential of mm‐Wave Doppler‐Polarimetric Profiler Observations for Quality Assessment of Hydrometeor Classification Schemes

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 11, 16 June 2025.
Abstract Dual‐polarization weather radars have improved the accuracy of precipitation estimates. However, challenges persist in evaluating hydrometeor classification (HMC) algorithms, thereby impacting the accuracy of precipitation estimates.

Exploiting the full potential of Doppler lidars: High‐resolution wind‐gust profiling in significant weather

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 769, April 2025 Part B.
The evolution of wind gusts is difficult to observe because gusts are short‐lived phenomena that can originate at higher altitudes. During the Field Experiment on Sub‐mesoscale Spatio‐Temporal Variability in Lindenberg (FESSTVaL), novel ground‐based remote‐sensing methodologies were applied to measure wind with Doppler lidars in order to provide the ...

Polarimetry for Sparse Multistatic 3D SAR

IET Radar, Sonar & Navigation
There is significant interest in multistatic SAR image formation, due to the increased development of satellite constellations and UAV swarms for remote sensing applications. The exploitation of the finer resolution and wider coverage of these geometries

Polarisation Synthesis Applied to 3D Polarimetric Imaging for Enhanced Buried Object Detection and Identification

Remote Sensing
Detecting sub-surface objects poses significant challenges, partly due to attenuation of the ground medium and cluttered environments. The acquisition polarisation and antenna orientation can also yield significant variation of detection performance ...

Ocean Wind Retrieval Models for RADARSAT Constellation Mission Compact Polarimetry SAR

Remote Sensing, 2018
We propose two new ocean wind retrieval models for right circular-vertical (RV) and right circular-horizontal (RH) polarizations respectively from the compact-polarimetry (CP) mode of the RADARSAT Constellation Mission (RCM), which is scheduled to be ...

Polarimetry of light scattered by surface roughness and textured films and periodic structures in nanotechnologies: a new challenge in instrumentation and modeling

EPJ Web of Conferences, 2010
Exhaustive studies in the literature detail the Mueller matrices properties through decomposition, optical entropy and depolarization formalism. It has been applied for many years in rather different fields. In radar polarimetry, mathematical basis of
