Geophysical Research Letters, Volume 51, Issue 16, 28 August 2024.Abstract Monitoring the generation and movement of equatorial plasma bubbles (EPBs) in a large longitude region is crucial important for better understanding their day‐to‐day variability. Using the newly developed Low lAtitude long Range Ionospheric raDar (LARID) at Dongfang (19.2°N, 108.8°E, dip lat.

Not So Fast: A New Catalog of Meteor Persistent Trains
Journal of Geophysical Research: Space Physics, Volume 129, Issue 7, July 2024.Abstract This paper presents the results of a nearly 2‐year long campaign to detect and analyze meteor persistent trains (PTs)—self‐emitting phenomena which can linger up to an hour after their parent meteor. The modern understanding of PTs has been primarily developed from the Leonid storms at the turn of the century; our goal was to assess the ...

IET Radar, Sonar &Navigation, Volume 18, Issue 7, Page 1055-1067, July 2024.The authors investigate the performance of an original multifunction system with two in‐band full‐duplex capable joint radar, communications and security transceivers in the presence of an eavesdropper. By combining a bandlimited pseudonoise waveform with an orthogonal frequency‐division multiplexing waveform, the authors are able to ensure a certain ...

Risk analysis of autonomous vehicle test scenarios using a novel analytic hierarchy process method
IET Intelligent Transport Systems, Volume 18, Issue 5, Page 794-807, May 2024.A novel analytic hierarchy process method is proposed to calculate the criticality of test scenarios for autonomous vehicles. In the proposed method, the pairwise comparison values can be automatically generated by the performance metrics from the simulation instead of the person involved.

Climatological model of over-the-horizon radar (CMOR)
, 2017 Models of radar systems are required for a variety of reasons. The sophistication of these models is highly dependant on their purpose; for instance microwave radar models which are designed to be integrated into existing wargaming simulation frameworks ...

FREQUENCY MANAGEMENT IN HF-OTH SKYWAVE RADAR: IONOSPHERIC PROPAGATION CHANNEL REPRESENTATION
, 2013 In High-Frequency (HF) Over The Horizon (OTH) radar, the space-time variations of the ionospheric channel, the external noise level (environment and man-made) as well as the transmission channel bandwidth limitations, are among the most critical and ...
