We are happy to welcome all our participants in Odessa - a beautiful Ukrainian city on the Black Sea coast. Odessa is the 3rd largest city in Ukraine and the largest city along the entire Black Sea. It gives you a feeling of being somewhere on the Mediterranean coast, since it has been heavily influenced by French and Italian art styles. For a few September days (5–11 September, 2016) the city is...
This paper discusses modern requirements for, and approaches to, design of a multi-sensor robotic radar system for humanitarian demining, and a through-wall imaging radar. In addition, we review progress in use of UWB radar systems for investigation of objects and structures representing important historical and cultural heritage. A review of the special European action intended for progress in civil...
The article offers a new option to create a Thunderstorm Warning System for the population. The main element of the system is a device that monitors the electric field strength in the atmosphere. The metal rod is used as a sensing element of the device. The device gives an alarm when reaching a dangerous level of the electric field. Information via mobile communication channels on a dedicated server...
Specifics of use of the Prony's method to determine the natural frequencies from the frequency response of the object in comparison with direct fractional-rational approximation has been examined.
A millimeter-wave (mmw: 3 mm wavelength, W-band) radar permits short-range, high-resolution detection and imaging of the airport movement area. The main safety-related applications, which have been tested in Marco Polo (Venice) and Urbe (Roma) airports respectively, are the prevention of runway incursions and the management of Foreign Object Debris (FOD). Other potential applications, to be studied,...
This paper describes briefly the basic ideas underlying different methods of determining the coordinates of objects by passive acoustic methods (passive acoustic location) for wideband acoustic signals, performs comparative analysis, and introduces a modified algorithm for localization of moving objects using the maximum of ambiguity function in application to passive acoustic localization of different...
In our review the developed electrodynamic numerical methods for modeling of scattering characteristics of complex-shaped electrically large and resonant radar objects are considered. Futures of mentioned numerical algorithms and their advantages in comparison with other well known techniques are discussed. Proposed algorithms allow obtaining frequency responses of air, ground, and subsurface radar...
With the creation and international standardization HDTV and UHDTV systems becomes an actual task of specification test signals to be used in the construction and maintenance video path and equipment of this systems. In this paper suggestions are made on the characteristics and parameters of test signals, that can be referred to basic: universal color bar signal used for evaluating quality of color...
The results of system spectral analysis of the unique registration of the gravitational waves generated by a binary black hole merger were proposed. On September 14, 2015 at 09:50:45 UTC two detectors of the Laser Interferometer Gravitational-Wave Observatory placed in the United States simultaneously observed a transient gravitational-wave signal. These were the first direct detection of gravitational...
cell answers to electromagnetic and magnetic fields are intensively investigated more than 50 years. In spite of huge amount of experimental data the general view on the problem depends of the personal point of view of investigator. Here we present main directions of investigation and most remarkable results of investigation of electromagnetic factors impact on cell in the last 5 years.
Electric current pulses of nanosecond length and amplitude up to 300 kV traveling through a transmission line partially filled with a magnetically saturated ferrite demonstrate excitation of quasi-monochromatic oscillations at 0.7–2.5 GHz. The amplitude efficiency of this DC-to-RF conversion can reach 50%. The two-dimensional model used for numerical analysis of the non-linear electromagnetic effects...
Experimental results and data of numerical simulations are presented, concerning generation of wideband radio frequency (RF) oscillations in a nonlinear transmission line (NLTL) which contains a pre-magnetized core of ferrite material. Emphasis is made on the means for extracting the RF signal from the line, in order to radiate it into free space. Antennas of two types that can be used for the purpose...
The problem of coupling between infinite and semiinfinite rectangular waveguides with different cross-sectional dimensions through a resonant slot in the end wall of the semiinfinite waveguide in the presence of resonant monopole is solved in a strict electrodynamic formulation. The monopole with variable surface impedance is placed parallel to the narrow walls at an arbitrary position inside the...
