Development of regression mathematical models of distortion of the radar information situation with the help of corner reflectors
Keywords:indicator, criterion, passive means of imitation, radio technical means, distortion, radar informative situation
A 3-D model of corner reflectors of various types and sizes was built on the basis of the analysis of the results of mathematical modeling using the CST Studio automatic decision-making system. As a result of the simulation, the numerical values of the parameters of the effective scattering area were determined, which made it possible to clarify the dependence of the relative change of the effective scattering area of corner reflectors on the shape of the rib, to confirm the hypothesis regarding the quadratic dependence of the effective scattering area on the radiation frequencies. A comparative analysis of the modeling results allowed us to conclude that for different observation angles, the effective scattering area of a small-angle reflector corresponds on average to the effective scattering area of a Mi-8T helicopter. It was also established that large corner reflectors with a rib size of 120 cm are the most appropriate for simulating fighter jets. At the same time, the weight of the corner reflector needs to be significantly reduced, which becomes possible when using light materials, such as foam plastic, which is pasted over with foil of the appropriate thickness. Electrodynamic modeling was confirmed by an experiment in an anechoic chamber. As a direction of further research, conducting experiments on changing the parameters of the effective scattering area of corner reflectors depending on a number of controlled factors was chosen.
