THE SIMULATION OF THE SCATTERING OF PULSES OF RADIO WAVES ON HOLLOW STRUCTURE
V. V. Kostyuchenko, N.A.Ankina
On the basis of the method, allowing a numerical solution of the full system of Maxwell’s equations, carried out the study of the scattering of a pulse with nanosecond duration of the three-dimensional hollow structure of rectangular cross-section. The calculation of the shapes of the reflected signals for different ratios between the spatial lengths of the pulses and the size of the diffraction structure. It was demonstrated that the value of the effective area of the scattering hollow structures with sizes close to the spatial length of the radar pulse, will be about the same as in the case of scattering long (monochromatic) pulses.
Keywords: momentum, scattering, hollow structure, Maxwell equations, finite difference method in the time domain.
THE SIMULATION OF SCATTERING CHARACTERISTICS OF OBJECTS HAVING EDGES
A. P. Preobrazhensky
In the paper the problems of scattering of radio waves on the objects, which include edge are considered. First, the analysis of the simplest edges, which is a wedge-shaped structure having a certain angle of solution is given. For the general case the edge of such structures may be truncated. The calculations of the scattering parameters was based on the method of integral equations in the framework of the Kirchhoff approximation. The examples of calculations of scattering characteristics are given, and built the radio image. Further the models of hollow structures is considered. The edges of these hollow structures can be defined by different edges. The calculations of the scattering parameters was based on the method of integral equations. The examples of calculations of scattering characteristics of hollow structures, and built the radio image of the edge part of the hollow structure.
Keywords: simulation, communication, diffraction, wave propagation, design, edge, hollow structure.
