Resolving Convective‐Scale Cloud and Precipitation Structures in Tropical Cyclone Rainbands With Novel Raman Lidar Observations

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Low‐level clouds in the tropical cyclone (TC) rainbands modulate the radial inflow of warm, moist boundary layer air, which can impact TC intensity. Yet, precisely measuring rainband cloud boundaries with existing remote sensing techniques remains a challenge.

Refining the Simulation of Mixed‐Phase Clouds Over Coastal Antarctica With a Tailored Ice Nucleating Particle Parameterization

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Climate models have substantial biases in downwelling shortwave radiation over the Southern Ocean (SO) and Antarctica, primarily due to their inability to accurately represent the frequent occurrence of low‐level mixed‐phase clouds. Building on the evaluation of the Unified Model (UM) Regional Atmosphere and Land version 3 (RAL3), this study ...

Doppler Problems in Orthogonal MIMO Radars

open access: yes2006 IEEE Conference on Radar, 2006
This paper presents a construction methodology waveform design with low cross-correlation, autocorrelation peak sidelobe levels and resilience to Doppler for orthogonal multiple-input multiple-output (MIMO) radar applications. It shows that an existing numerical solution only addresses autocorrelation and cross-correlation properties with the result ...

Integrated Sensing and Communication in a Fiber‐Wireless System With Time‐Phase Synthesis Dimension Waveform

open access: yesNanophotonics, Volume 15, Issue 17, 11 September 2026.
A unified fiber‐wireless integrated sensing and communication system is enabled by a single microwave photonic platform with a time‐phase synthesis dimension waveform. This architecture simultaneously delivers high‐speed data transmission, high‐precision wireless ranging, and accurate fiber diagnostics over a high‐power analog radio‐over‐fiber link ...

Flow angle dependence for the asymmetry of broad 50-MHz coherent echoes at large magnetic aspect angles [PDF]

open access: yes, 1997
International audienceThe skewness of broad Type 2-like spectra has been studied using data collected by two orthogonal CW 50-MHz radio links with co-located scattering volumes. Geometrical aspect angles of observations were about 10°.

Application of S-Transform Random Consistency in Inverse Synthetic Aperture Imaging Laser Radar Imaging

open access: yesApplied Sciences, 2019
Under the same principle, laser radar could be more sensitive to the micro-Doppler (m-D) effect due to its wave length, as the characteristic of multi-resolution, S transform could reduce the influence of the micro-Doppler component and enhance the ...
