Abstract
This paper demonstrates that mathematical modeling makes it possible to build and explore radiolocation profiles of modern and advanced aircraft. Construction and studying mathematical models based on modern information and computer technology can implement methods for calculating the characteristics of secondary radiation of aircraft at required accuracy, in order to ensure their practical feasibility. We have substantiated a method for the calculation of characteristics of aircraft secondary radiation to analyze the radiolocation scattering of the Su-25T attack aircraft model. The advantage of this method is taking into consideration the integrated representations of classical electrodynamics and shortwave asymptotics. A model of the surface of Su-25T aircraft has been built and a method of mathematical modeling has been constructed. The basic characteristics of radiolocation scattering of aircraft have been substantiated ‒ the effective surface of scattering, the non-coherent effective surface of scattering, average and median values for the effective surface of scattering, the distribution laws of the amplitude multiplier of reflected signal. The paper reports results of calculation of these characteristics for the radiolocation scattering of Su-25T aircraft for different radiation frequencies of the probing signal. The obtained results are proposed for application during modernization and design of promising means of radiolocation. The results presented here are useful to assess the feasibility of different structural variants of such tools aimed to detect, track, and recognize aircraft of the same type. Application of the results obtained would make it possible to optimize the design of modernized and promising aircraft in order to reduce their radiolocation visibility. The proposed method is the basis for mathematical modelling of radiolocation characteristics of different types of aircraft under the assigned spatial and time-frequency parameters of probing signals, in order to solve the applied tasks on radiolocation
Highlights
The availability of data on the characteristics of secondary radiation of an aircraft makes it possible to solve several practical tasks on radiolocation
Further development of this research could be the introduction of necessary changes to the proposed model and the principles of modeling taking into consideration the internal and external influences on the radiolocation characteristics of aircraft at flight
It is shown that it is necessary to split the surface of the plane into two groups: a smooth part of the surface and the edge local scattering sections
