We describe observations of a trend between the level of km-scale irregularity activity and
the amplitudes of medium-scale traveling ionospheric disturbances (MSTIDs) at mid …

The detection performance of high frequency surface wave radar (HFSWR) and high
frequency over-the-horizon radar (OTHR) systems is heavily influenced by the presence of …

Various radio wave instruments and technologies operating in the High Frequency (HF)
radio band have been used for many decades and are reliant on or are affected by the …

Models of radar systems are required for a variety of reasons. The sophistication of these
models is highly dependent on their purpose; for instance, microwave radar models, which …

This comprehensive guide helps readers understand the theory and techniques needed to
analyze and model radio wave propagation in complex environments. All of the essential …

Radars performing observations of resident space objects (RSO) measure Doppler
variations in wave events of several minutes duration, with frequencies in the 0.2-1 Hz range …

Climatological models of the ionosphere, such as the International Reference Ionosphere
(IRI), are often used to assess the performance of over the horizon radar (OTHR) over the …

High frequency (HF) radio waves propagating through regions of ionospheric plasma
irregularities exhibit random fluctuations in both amplitude and phase referred to as …

In this paper, we explored how to more accurately predict the quality of high-frequency links
and how to better research and improve the capabilities of high-frequency communication …

The ionospheric impact of a series of M‐class solar flares that occurred on 12 March 2015 is
described. A combination of data sets from GPS receivers and two different colocated radio …
