“GuidesArray Circular”

With this program you can execute mathematical modelling by the phased periodic plane antennas array from circular wave guides in sector of angles and a band …

 



GuidesArray Circular is supposed for purposes of modeling of phased antenna arrays created using circular waveguides. Such antenna arrays can be used as transmit \ receive antenna systems for radio- and television-broadcast centers, cellular and paging …


With this program you can execute mathematical modelling by the phased periodic plane antennas array from circular wave guides in sector of angles and a band of frequencies.
The offered mathematical model is founded on an electrodynamic solution of a boundary task in a unit mesh of infinite structure.

“Boundary waves and characteristics of slot array”

One of the most efficient methods of numeric research of characteristics of finite antenna arrays is the method suggested in [1]. This method is based on the transformation …

 



The results of the research of characteristics of a finite slot phased array are given. It is shown that boundary waves cause significant change of a side radiation in large arrays when the beam deviation in a single scan sector is at maximum. …


One of the most efficient methods of numeric research of characteristics of finite antenna arrays is the method suggested in [1]. This method is based on the transformation of the mutual resistance matrix into a circulant matrix and iterative procedure of solution of the system of linear algebraic equations with the transformed matrix. Also efficient is another method based on the concept of boundary waves [2], which states that the distribution of current in a finite antenna array with uniform amplitude and phase distribution of waves propagating in the feeder lines, can be represented as a sum of the regular part and the boundary wave propagating from the border of the radiating matter deep into the array...
 



In section of “Publications-Books” the “Basic energy correlations in the analysis of the effectiveness of aircraft anti-radar camouflage” book is published. Author: V. N. Yudin.


In the book deals with the quantitative analysis of how effective it is to hide aircraft from radar surveillance with the help of camouflage jamming.
