  • Geomagnetic Pulsation Amplitude and Spectrum Variations Accompanying the
           Ionospheric Heating by High-Power Radio waves from the Sura Facility
    • Abstract: Aperiodic and quasiperiodic variations in the geomagnetic pulsation amplitude in a range of periods from 40 to 1000 s, which accompany the quasicontinuous and periodic impact on the ionospheric plasma by high-power radio waves from the SURA facility near Nizhny Novgorod (Russia) were recorded near Kharkov (Ukraine) using a magnetometer–fluxmeter. The main parameters of aperiodic and quasiperiodic disturbances of the geomagnetic field are determined. The mechanisms for generation and propagation of detected disturbances are discussed.

  • On the Impact of Eddy Motions in the Mesosphere and Lower Thermosphere on
           the Evolution of the Signal Scattered by Artificial Periodic
           Irregularities
    • Abstract: The main objective of this study is experimental diagnostics of eddy ordered structures at the altitudes of the mesosphere and upper thermosphere, such as those that occur when internal gravity waves propagate in stratified flows in the atmospheric boundary layer. To this end, we consider the impact of eddy motions in the mesosphere and lower thermosphere during relaxation of the signal scattered by periodic irregularities. The irregularities are created by a standing wave when the ionosphere is heated by high-power HF radio waves. A model of a uniform eddy with sizes exceeding the scattering volume is used. A relation between the eddy period and the characteristic time of relaxation of scattered signal, for which the synchronism of the waves scattered by a periodic structure is broken, is found. This, in turn, decreases the amplitude of the scattered signal and its relaxation time. Experimental data on atmospheric turbulence obtained by the resonant scattering technique are presented.

  • Peculiarities of Operation of a Relativistic Backward-Wave Oscillator
           Driven by an External Electromagnetic Signal
    • Abstract: We study operation of a relativistic backward-wave oscillator driven by an external electromagnetic signal. Such operation regimes as hard excitation of self-oscillations and amplification of the external signal are implemented experimentally. The conditions for possible synchronization of the relativistic backward-wave oscillator by an external signal is discussed. The possibility of accelerating the onset of oscillations by the action of an external signal is confirmed experimentally. The conditions of realization of the amplification regime and the main effects, which limit the amplification coefficient, are determined. The obtained results can be used to optimize the parameters of generators and amplifiers based on relativistic backward-wave oscillators.

  • Features of the Shock-Wave Generation In High-Intensity Bounded Acoustic
           Beams in the Presence of a Soft Boundary in the Interaction Region
    • Abstract: This paper is devoted to experimental studies of interaction between intense acoustic fields and their interfaces. In particular, we discuss the results of experimental studies of the spatial variation of the profile and spectrum evolution of an intense acoustic wave reflected from an acoustically soft boundary. The distance between the source aperture and the surface approximately corresponds to the coordinate of the last diffraction maximum in the axial distribution of the acoustic field at the pump frequency. The radiation intensity was chosen in such a way as to ensure the nonlinear wave interaction both before and after the reflection. It is shown that antiphased interaction between harmonics in the reflected wave formed before the boundary and the harmonics formed after the refection leads to a significant variation in the profile and spectrum of the reflected wave, which determines the further formation of nonlinear waves. Propagation of the reflected wave is accompanied by an intense rise in signal amplitude in the compression phase and the formation of a new shock-wave front. A nonmonotonic decay as a function of the harmonic number is observed in the harmonic amplitude distribution. This feature of the spectrum behavior takes place in the increasingly low-frequency part of the spectrum as the distance from the boundary increases.

  • On the Doppler Frequency Shifts of Radar Signals Backscattered from the
           Sea Surface
    • Abstract: We study the frequency spectra of the radar signals scattered from the wind waves on the sea surface in the full-scale experiment. Two types of the radar Doppler shifts of the spectrum maximum, namely, the averaged shift of the instantaneous spectrum of the scattered signal and the shift of the maximum of the signal time-averaged spectrum as functions of the incidence angle and the wind velocity and direction are analyzed for different sounding-wave polarizations. Significant difference between the average shift of the instantaneous spectrum and the shift of the average-spectrum maximum is demonstrated. This difference is attributed to the radar-signal modulation effect in the field of long surface waves. The obtained results are very important for correct retrieval of the velocities of the surface currents using the data of the satellite-borne measurements of the radar Doppler shifts.

  • Quasi-Standing Wave Dragging Effect in a Rotating Ring Laser in the
           Presence of an Optical Medium
    • Abstract: We consider quasistanding waves in a rotating ring laser, whose nodes and antinodes are immobile with respect to the inertial reference frame in the absence of an optical medium in the resonator. In this case, the nodes and antinodes of the quasistanding waves rotate with the laser rotation velocity with respect to the reference frame which rotates along with the ring laser. It is shown that the quasistanding-wave motion in the rotating reference frame slows down a factor of n2 if an optical medium with the refractive index n is present in the ring laser. In this case, the waves move with respect to the inertial reference frame with a velocity that is proportional to the Fresnel dragging coefficient 1 – 1/n2.

  • Principles of Designing an “Ideal” System of Imaging Through a
           Rough Water Surface
    • Abstract: We propose new principles for designing a system of imaging through a rough water surface. These principles permit one to reduce the negative impact of the surface roughness and multiple scattering in water on the spatial resolution. The system model in which the image of underwater objects is generated by angular scanning with an illumination beam is considered. Image distortions in such a system are due mainly to random variations in the refraction angle of a laser beam on the surface and can be eliminated if the true direction of entry of the beam into water is known. Information on the beam refraction angle is suggested to be taken from the angular distribution of the radiance of the signal backscattered by the subsurface water layer. Reduced impact of multiple scattering in water is reached by high-frequency modulation of the beam power by a complex signal and matched processing in the reception system. It is shown that a combination of proposed imaging techniques gives an essential gain in the resolution of the airborne imaging system.

  • Quasioptimal Estimation of Motion Parameters Based on Laser Ranging
    • Abstract: An algorithm for estimation of range, velocity, and acceleration based on measurements of range in each repetition period of the probing sequence of optical pulses is synthesized. Characteristics of estimates with allowance for abnormal errors are found. It is shown that the proposed estimates are consistent, asymptotic (the signal-to-noise ratio increases for each pulse), unbiased, and effective.

  • On Using Cyclotron Waves for Output of Radiation from High-Power
           Relativistic Backward-Wave Oscillators
    • Abstract: We discuss the scheme of a high-power relativistic backward-wave oscillator operating with a high-current explosive-emission electron beam. The radiation output from the tube is based on reflection of the operating wave into a fast cyclotron wave which transmits the energy of the high-frequency field towards the collector. At the collector, reverse conversion into the output electromagnetic wave takes place. The proposed scheme allows one to increase electric strength, as well as the transverse size of the working space of the backward-wave oscillator. It is shown that within the proposed scheme, one can reduce the focusing magnetic field without decreasing the power of the output radiation.

  • Bandpass Filters Based on L-ridged Rectangular Waveguides
    • Abstract: We solve the problem of electrodynamic analysis and synthesis of bandpass filters based on rectangular waveguides with complex L-shaped ridges. Cutoff wave numbers and components of the electromagnetic field were calculated by the partial region method with allowance for the singularity of the electromagnetic field on metal ribs. As a prototype, the model of a cutoff filter and an approximation of its amplitude-frequency characteristic by the Chebyshev polynomials were used. Examples of synthesis of narrow-band filters with inputs based on a rectangular waveguide and an H-waveguide are presented. Advantages of using a novel waveguide with a complex cross section in the filter are considered, including the appearance of a total reflection frequency (antiresonance) in the filter rejection band, which allows one to significantly extend this band and increase the attenuation level in it.

    • Abstract: We generalize a version of the auxiliary-source method, which was proposed earlier to solve the problem of scattering of an electromagnetic field by a single thin dielectric cylinder, to the case of a structure consisting of several noncrossing cylinders of such a type. The specially developed computer code is briefly described. The results of numerical calculations of the scattering cross sections for some particular structures are reported.

  • Impact of the Elf Receiver on Characteristics of the Observed Q-bursts
    • Abstract: We consider the impact of a typical Schumann-resonance receiver on the waveforms of the ELF transients, or Q-bursts. For this purpose, the Q-bursts were calculated both in the frequency and the time domains. The data obtained within the framework of the frequently used models of the propagation constant are compared. The effect of a typical ELF receiver containing a 4–40-Hz bandpass filter combined with a 50-Hz notch filter is evaluated. The main attention is given to distortions in the pulsed signal waveform. It is found to what extent a Schumann-resonance receiver retards the pulse, how the ratio between the amplitudes of the positive and negative half-waves at the pulse front is modified, and how the antipodal and round-the-world subpulses are distorted. Since such distortions are able to impede correct identification of the ELF pulses and determination of the source polarity and the source-to-observer distance, we discuss the possible ways of compensating for the deformations produced by the receiver.

  • Small-Scale Turbulence of the Earth’s Magnetosheath
    • Abstract: We present the results of experiments on reception of the Sura facility signals in the 9-MHz range using the WIND spacecraft. The technique of determining the temporal spectrum of the Earth’s magnetosheath plasma irregularities with less than 100-km scales based on the radio scintillation spectrum in terms of the weak scattering theory is proposed and implemented. Using the in situ measurements of the electron number density onboard spacecraft with a temporal resolution of about 3 s, it has been found that the inner scale of the magnetosheath turbulence varies within 10–90 km with a mean value of about 30 km.

  • Analysis of the Throughput of the Cellular Radio-Communication Systems
           Using Coordinated Data Transmission to Suppress Mutual Unintended
           Interference
    • Abstract: We present the results of the comparative analysis of two data-transmission schemes of the fourth-generation cellular communication standard LTE-A, which use the “quasistatic” and “dynamic” coordination at the neighbor base stations. Both schemes are used to suppress mutual unintended co-channel interference resulting from the repeated use of one frequency channel by the neighbor base stations. The general case of the heterogeneous cellular radio-communication system with different station types (macro- and picostations) is considered. In this work, the efficiency of the coordinated-transmission schemes is studied along with the adaptive algorithms for the dataflow planning and control. The use of both coordination schemes is comparatively analyzed. An original algorithm for redistribution of the user connections is proposed for the dynamic scheme and the dependence of the communication-system throughput on the radio-network configuration and the number of base stations, that participate in the coordination is studied.
