Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Equatorial plasma bubbles (EPBs) pose significant challenges to trans‐ionospheric radio communication and navigation systems. Because of their disruptive effects, evaluating and predicting them is key for the development of space systems. The influence of geomagnetic activity on EPBs remains unclear, partly due to limited low‐latitude neutral ...

Hand Gesture Recognition Using Micro-Doppler Signatures With Convolutional Neural Network
IEEE Access, 2016 In this paper, we investigate the feasibility of recognizing human hand gestures using micro-Doppler signatures measured by Doppler radar with a deep convolutional neural network (DCNN).

Data analysis techniques: Spectral processing [PDF]
, 1983 The individual steps in the data processing scheme applied to most radars used for wind sounding are analyzed. This processing method uses spectral analysis and assumes a pulse Doppler radar.

Space Weather, Volume 24, Issue 1, January 2026.Abstract Accurate modeling of traveling ionospheric disturbances (TIDs) is essential for characterizing their spatiotemporal variations and mitigating their effects on Global Navigation Satellite System (GNSS) precise positioning. This study develops a regional medium‐scale TID (MSTID) propagation model using BeiDou geostationary orbit (GEO) total ...

Freshly Generated Super Sunrise Plasma Bubbles During the Geomagnetic Storm on November 5–6, 2023
Space Weather, Volume 24, Issue 1, January 2026.Abstract During the geomagnetic storm on November 5–6, 2023, freshly generated super sunrise equatorial plasma bubbles (EPBs) and associated irregularities over the 80°–140°E sector were observed combining ground‐based and space observations from GNSS, ionosondes, HF Doppler records, and several satellite missions (COSMIC2, Swarm, and DMSP).

Remote temperature profiling in the troposphere and stratosphere by the radio-acoustic sounding technique [PDF]
, 1986 Radar application of the radio-acoustic sounding technique uses the Doppler frequency shift of radar echoes returning from the atmospheric wave structure, in association with a traveling acoustic pulse transmitted from the ground, to determine the speed ...
