On the Ion Line Calibration by Plasma Line in ISR Measurements

Remote Sensing, 2023
The radar constant calibration in incoherent scatter radar ion line processing is essential for the data quality and was not paid enough attention in previous studies.

Thermospheric Parameters during Ionospheric G-Conditions

Remote Sensing, 2021
For the first time thermospheric parameters (neutral composition, exospheric temperature and vertical plasma drift related to thermospheric winds) have been inferred for ionospheric G-conditions observed with Millstone Hill ISR on 11–13 September 2005 ...

The Validation of FORMOSAT-3/COSMIC Measurements in the Middle Latitude Region of China with Ionosonde Observations during 2015–2018

Universe, 2022
We used ground-based ionosonde observations at Ganzi (31.2° N, 100.4° E) to validate the COSMIC measurement in the middle latitude region of China during low solar activity.

Experimental Observation and Analysis of Ionosphere Echoes in the Mid-Latitude Region of China Using High-Frequency Surface Wave Radar and Ionosonde

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Ionospheric clutter is a major factor affecting the performance of high-frequency surface wave radar (HFSWR). Previous studies have been mainly focused on the development of ionospheric clutter suppression methods involving delicate signal processing ...

A Comparative Study on Radio Frequency Interference Suppression and foF2 Scaling for Ionograms

Remote Sensing, 2023
In this paper, we compare the performances of radio frequency interference (RFI) suppression between radio frequency interference mitigation (RFIM) and frequency-domain adaptive clutter suppression (FACS) algorithms that apply to ionograms for foF2 ...

The Comparison of Electron Density between CSES In Situ and Ground-Based Observations in China

Remote Sensing, 2022
As the observation accuracy of parameters in the ionosphere cannot be directly checked, the comparison with other observations is the main way to evaluate the data quality of satellite measurements.

Calibrating an Ionosonde for Ionospheric Attenuation Measurements [PDF]

Sensors, 2018
Vertical ionospheric soundings have been performed at almost all ionospheric observatories with little attention to measuring the attenuation of the signal between transmission and reception. When the absorption has been determined, this has been achieved by comparing the received power after the first and second reflections, but this method has some ...
