The previously obtained integral field representation in the form of double weighted Fourier transform (DWFT) describes effects of inhomogeneities with different scales. The first DWFT approximation describing the first-order effects does not account

We have used numerical simulation to study the effects of ionospheric irregularities on accuracy of global navigation satellite system (GNSS) measurements, using ionosphere-free (in atmospheric research) and geometry-free (in ionospheric research) du

Phase and amplitude fluctuations (scintillations) are recorded when a signal of the global navigation satellite system (GNSS) passes through the anisotropic, randomly inhomogeneous ionosphere. In this case, the Earth’s magnetic field exerts a doubl

We study the possibilities of integral representation for the two-frequency mutual coherence function of the wave field in a randomly inhomogeneous ionosphere. The integral representation was obtained using the Double Weighted Fourier Transform (DWFT

To analyze inhomogeneities, it is appropriate to use phase tomography, which is based on the measurement of the phase of a wave transmitted from a transmitter to a receiver. Physical parameters of inhomogeneous media are identified by these methods i

In the geometrical optics approximation, the ionospheric part of error in measuring phase and code delays of the satellite signal may be represented as a rapidly decreasing series in inverse power of frequency. Such a simple frequency dependence allo

The report solves the inverse problem of diagnostics of inhomogeneous plasma through spatial field processing in the form of inverse double weighted Fourier transform (DWFT). As an inhomogeneous medium, we use a model in the form of three Gaussian ir

It is known that ionospheric irregularities have an adverse effect on radio wave propagation, especially in polar regions. The main feature of ionospheric irregularities is their multiscale character. Accordingly, various methods for describing radio

This paper presents the results of scattered wave field simulation in inhomogeneous plasma media. The double weighted Fourier transform was selected as a model of scattered field. We consider several cases: wave scattering in a local plasma inhomogen

When using global navigation satellite systems (GNSSs) for high-precision measurements, one should consider high-order errors. The ionospheric second-order error caused by the geomagnetic field is approximately proportional to the total electron cont
