Climatology of Spread F over Tucumán from Massive Statistical Analysis of Autoscaled Data

open access: yesAtmosphere, 2021
Automatic ionogram interpretation methods developed for real-time ionospheric monitoring can be applied in retrospective studies to analyze large quantities of data. The Autoscala software, implemented for such a purpose, includes a routine for automatic

New low power pulse compressed ionosonde at Gibilmanna Ionospheric Observatory

open access: yesAnnals of Geophysics, 2005
A digital low power pulse compressed ionosonde was developed at the Istituto Nazionale di Geofisica e Vulcanologia (INGV), Rome, Italy. The aim of this Advanced Ionospheric Sounder, AIS-INGV, is to reduce the transmitted power and, consequently,

Chaotic Coding for Interference Suppression of Digital Ionosonde

open access: yesRemote Sensing, 2023
External interference in ionospheric sounding seriously degrades the quality of echo signals and data; thus, it should be eliminated. This paper presents a method for suppressing interference using chaotic coding with a set of Bernoulli map sequences; compared with other commonly used coding methods such as Barker code, complementary code, and Barker ...
