Study of waves observed in the equatorial ionospheric valley region using Jicamarca ISR and VIPIR ionosonde
Incoherent scatter (IS) radar and ionosonde (VIPIR, vertical incidence pulsed ionospheric radar) data were taken concurrently at Jicamarca during campaigns of January, April, June, and July 2015, January 2016, and most recently April 2017 to bring more insight into the state and dynamics of the …

Ionospheric Sounding During a Total Solar Eclipse
… back downwards is a core principle of an ionosonde, which measures the height of the ionosphere. A solar eclipse presents a night side ionosphere condition during the day. The change in the ionosphere that the eclipse will cause is something not a lot of research has gone into. This thesis …

A Standalone High Frequency Receiver System
… RF recording system that is designed to pick up ionosonde sounding signals from 1—10 MHz. Systems are designed for quick deployment and capable of remaining deployed in the field for up to a month. The design motivation was for ionospheric sounding campaigns in New Mexico organized by the Air …

Intense spreading of radar echoes from ionospheric plasmas
… for X and O mode waves transmitted from an ionosonde and an analysis of the collisional Rayleigh-Taylor instability leading to an expression for the growth rate are presented as background information. Ray tracing code developed by Nathan Dalrymple, a previous graduate student of Professor …

Characterising Spatial and Temporal Ionospheric Variability with a Network of Oblique Angle-of-arrival and Doppler Ionosondes
… of oblique angle-of-arrival (AoA) and Doppler ionosondes were installed in central and northern Australia as part of the ELOISE campaign in 2015. This thesis analyses observations from the ELOISE AoA ionosondes, with a focus on characterising the influence of medium- to large- scale gradients …

Pulse Coding for ionospheric radar
CADI (Canadian Advanced Digital Ionosonde) is an active radar, which is used to probe the structure and motion of the ionosphere, such as virtual height, drift velocity, angle of arrival, echo intensity, etc. It is mainly composed of a control platform (like a personal computer PC), the plug-in DDS …

Study of Coulomb collisions and magneto-ionic propagation effects on incoherent scatter radar measurements at Jicamarca
… The inversion results show a good agreement with ionosonde data, validating our model for incoherent scatter radar measurements.
