Performance of the Colorado wind-profiling network, part 1.5A [PDF]

open access: yes
The Wave Propagation Laboratory (WPL) has operated a network of radar wind Profilers in Colorado for about 1 year. The network consists of four VHF (50-MHz) radars and a UHF (915-MHz) radar.

The Adelaide MF partial-reflection radar and VHF ST radar [PDF]

open access: yes, 1986
The microwave frequency (MF) partial-reflection radar ran continuously since November 1983, with data being analyzed in real time. The spaced antenna technique was used routinely to produce a climatology of the mean circulation, atmospheric tides, and ...

Dynamic Response of Spherically Curved Laminated Plate Subjected to Sudden Loading

open access: yesJournal of Engineering, Volume 2026, Issue 1, 2026.
This study investigated the dynamic response of simply supported spherical laminated composite plates with square vertices, composed of graphite/epoxy material, under sudden loading. The research examined the influence of stacking sequence, thickness variation, and type of loading using the finite element method (FEM).

Monitoring Bridge Vibrations via Spaceborne SAR Micro‐Doppler

open access: yesStructural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
The advent of Synthetic Aperture Radar (SAR) imaging has presented the possibility of remote monitoring of civil infrastructure on a large scale. Although well established for observing slow and long‐term phenomena, its application to vibration‐based structural health monitoring (SHM) remains relatively unexplored in the current literature.

A Noncontact Methodology for Disengagement Monitoring of High‐Speed Railway Bridge Bearings Based on Bearing‐to‐Beam Displacement Relation Under Round‐Trip Trains

open access: yesStructural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Bearings are critical components of bridges and are susceptible to various forms of deterioration under the action of traffic loads and complex environmental conditions. Existing methods for assessing the condition of bearings, including visual inspections, force sensors, cameras, and vibration sensors, still present challenges in accurately locating ...
