Non-standard radio wave propagation in the atmosphere is caused by anomalous changes
of the atmospheric refractivity index. In recent years, refractivity from clutter (RFC) has been …

We address the problem of tracking the spatial and temporal lower atmospheric variations in
maritime environments. The evolution of the range and height-dependent index of refraction …

Atmospheric ducts, which are caused by the rapid decrease in the refractive index of the
lower atmosphere, can trap the propagating signals. The trap** effects of the atmospheric …

This paper describes a Markov chain Monte Carlo (MCMC) sampling approach for the
estimation of not only the radio refractivity profiles from radar clutter but also the …

Inversion of atmospheric ducts is of great importance in the field of performance evaluation
for radar and communication systems. Since the model parameters in machine learning play …

Tropospheric duct is an anomalous atmospheric phenomenon over the sea surface that
seriously affects the normal operation and performance evaluation of electromagnetic …

An evaporation duct, which often occurs in the air–sea boundary layer, has a considerable
impact on the remote sensing detection capability of electromagnetic (EM) systems. Tropical …

This paper estimates lower atmospheric refractivity (M-profile) given an electromagnetic
(EM) propagation loss (PL) measurement. Specifically, height-independent PL …

This article explores the effects of system frequency on electromagnetic (EM) remote
sensing of atmospheric refractivity. A frequency range of 2–40 GHz covering S-to Ka-bands …

Atmospheric duct parameters inversion is an important aspect of microwave-band radar and
communication system performance evaluation. AIS (Automatic Identification System) is one …
