Application of matched filtering for processing ultra-wideband signals
Engineering Education # 10, October 2013 DOI: 10.7463/1013.0623000 The author considers a possibility of using matched filtering of UWB signals. Maximum achievable characteristics of UWB systems make them promising for many application domains such as data transmission systems, medical systems, security systems, radars, etc. Processing is possible with the use of special filtration devices created on the basis of irregular transmission lines with the T-wave, in particular, on the basis of matched filters, which is the main topic of this paper. For a UWB sounding signal duration is much shorter than duration of a signal reflected from the target; therefore, it could be taken as a sampling period. In this case, application of preliminary matched filtering of the reflected signal, followed by traditional processing, is possible.
A statistical model of the market sector of macroeconomic management
Engineering Education # 06, June 2013 DOI: 10.7463/0613.0586255 The author considers a statistical model of the market sector of the macroeconomic management system, where supply and demand lack any regular pattern due to the statistical spread of customers’ incomes and sellers’ profitability. Probability density distribution of customers’ incomes and sellers’ profitability was determined on the basis of studying market statistics. Using these distributions it was possible to obtain distribution density of possible supply and demand over the market price. Natural and monetary sales volumes, mean price, supply and demand dynamics were also determined. A feature of this model is simultaneous existence of an unsatisfied demand and a stock in trade, which, for example, is typical for the labor market.
Analysis of dispersion characteristics of linear elements’ line parameters of UWB balanced printed cavity antennas of a travelling wave
Engineering Education # 04, April 2013 DOI: 10.7463/0413.0548171 The authors carried out an electro-dynamic analysis of the line parameters’ dispersion characteristics of the segments of balanced stripline-slot antennas of traveling waves with different configuration. A dispersion model of the twin-strip line was presented. Dispersion equations were obtained by reduction of the original system of integral equations relating the currents and the electric fields in the cross section of the transmission line to a homogeneous system of linear algebraic equations by means of the spectral Galerkin method. In order to find the components of the two-dimensional Green tensor function the method of spectral immitances was used. Analysis of test line geometries was carried out.

Engineering Education # 03, March 2012 The author considers the renovation process in Kalman-Bucy optimal filter and proposes a solution of the differential equation for tracking error. It is shown that this solution includes normalized impulse characteristics. The expression for the renovation process correlation matrix is included in this article.

77-30569/247762 Development and study of a modified Vivaldi aerial as part of a flat wideband X-band antenna array
Engineering Education # 11, November 2011 This paper presents the results of development of radiators for ultrashot impulse wideband X-band printed phased antenna arrays. Ultra-wideband travelling wave slot Vivaldi antenna was studied and adapted for radiation at X-band as an effective wideband radiator with required characteristics. The modification of this aerial is presented. Matching characteristics and radiation patterns were obtained both for single radiator and for radiator in periodic flat antenna array.
