Wave‐Based Quantification of Ion Composition in the Earth's Magnetosphere‐Ionosphere‐Coupling Region
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Ion composition critically determines the basic kinetic characteristics of plasma and affects energy transmission of the magnetosphere. However, it exhibits significant variations with altitude, latitude, local time, longitude, and also with geomagnetic and solar activity.

Convolutional Radio Modulation Recognition Networks
, 2016 We study the adaptation of convolutional neural networks to the complex temporal radio signal domain. We compare the efficacy of radio modulation classification using naively learned features against using expert features which are widely used in the ...

SOME RADAR TOPICS: WAVEFORM DESIGN, RANGE CFAR AND TARGET RECOGNITION [PDF]
, 2006 The first RADAR patent was applied for by Christian Huelsmeyer on April 30, 1904 at the patent office in Berlin, Germany. He was motivated by a ship accident on the river Weser and called his experimental system ”Telemobiloscope”. In this chapter some important and modern topics in radar system design and radar signal processing will be discussed ...

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Narrow bipolar events (NBEs) are often generated in overshooting thunderclouds (OT) penetrating the stratosphere. However, how and under what conditions OT produces such discharges remains unclear. With 3‐year lightning observations and simultaneous cloud top brightness temperature measurements over South China, we developed a more accurate OT

Multiple frequency range imaging to remove measurement ambiguity [PDF]
, 2009 Range imaging systems use a specialised sensor to capture an image where object distance (range) is measured for every pixel using time-of-flight. The scene is illuminated with an amplitude modulated light source, and the phase of the modulation envelope

Data management, chapter 5, part C [PDF]
The data management for a spacecraft radar was defined in terms of an end-to-end data system, which performs the following three functions: (1) sampling and compaction of data onboard the spacecraft, (2) manipulation of radar data on the ground and (3 ...
