Abstract

Background. Modern standards of development and production of complex systems require you to perform testing and confirmation of the tactical-technical characteristics in the early stages of the product life cycle. The relevance evaluation of the work of the Simulator as a part of a complex of semi-natural simulation confirmed the possibility of taking into account all basic parameters of training Simulator provides possibility of environment for functional verification of algorithms of search, seizure, guidance and accompaniment goals. The basis behind complexes of semi-natural simulation uses the presentation model training Simulator provides possibility of the situation taking into account the characteristics of the reflection of radar signals from a given set of types, objects and purposes underlying surfaces.
Materials and methods. Complex reflection (backscatter) electromagnetic fields are simplified by replacing the spatial-electrical
characteristics of surface targets, Earth, water on the relevant characteristics of the reflected signal, known for the selected carrier frequencies ranges from analysis and synthesis of data field experiments. In a hardware implementation model of space distribution of direct and indirect signals between radar and antennas throughout the reflective surface is presented in the form of a multi-channel model, which greatly simplifies the analysis.
Conclusions. It is shown that for the formation of the radar echoes model with variable parameters radar implementations of summation (mixing) copies of probing signal with different delays, amplitudes, frequency shifts. Calculation of parameters for the specified number of channels forming, as well as their transfer signal simulator based on modules in real time, allowing the grouping of reflectors on the basis of the simulation of the system taking into account the angle evolutions and speed of aircraft directional aerials and chart settings properties of the underlying surface.
