Designing of a visual simulation Simulink application for modeling adaptive algorithms for the protection of radars of radio engineering troops against active noise interference

Designing of a visual simulation Simulink application for modeling adaptive algorithms for the protection of radars of radio engineering troops against active noise interference

Abstract

The article gives the general principles for designing a visual simulation application for modeling adaptive algorithms for protecting radar stations of the radio engineering troops against active noise interference. The designing was made using the Simulink visual modeling software package of the MATLAB system. As adaptive protection algorithms, an active noise interference compensation algorithm with correlative feedback connection and direct calculation of weight coefficients was used. The correctness of the results of the Simulink application was confirmed during the experiment, where the simulated active noise interference, intrinsic noises of the main and additional receiving channels and echo signals of the target were input to the model. Simulation results are presented using the Scope component (oscilloscope) of the Sinks block library of the Simulink package. Recommendations are also given on the inclusion of the proposed application in the educational process of a technical university as a visual didactic learning tool.

У статті викладено загальні принципи проєктування візуально-імітаційного додатка для моделювання адаптивних алгоритмів захисту радіолокаційних станцій радіотехнічних військ від активних шумових завад. Проєктування проведено за допомогою пакета програм візуального моделювання «Simulink» системи «MATLAB». Алгоритм компенсації активних шумових завад з кореляційним зворотним зв’язком і прямим розрахунком вагових коефіцієнтів використовувався як адаптивний алгоритм захисту. Правильність результатів роботи Simulink-додатка була підтверджена під час проведення експерименту, де на вхід моделі надходили імітовані активні шумові завади, власні шуми основного та додаткового каналів прийому та ехосигнали цілі. Результати моделювання подані за допомогою компонента Scope (осцилограф) бібліотеки блоків Sinks пакета програм візуального моделювання «Simulink». Також надано рекомендації стосовно залучення запропонованого додатка до навчального процесу технічного університету як візуального дидактичного засобу навчання.
