Abstrakt
W artykule zaproponowano udoskonaloną metodę analizy widmowej sygnałów radiowych. Poprawę osiąga się dzięki zastosowaniu specjalnych operatorów w procesie konwersji sygnału. Pozwala to na dokładne rozróżnienie sygnału i określenie jego charakterystyki na tle wielu przeszkód w przestrzeni powietrznej. Uzyskane wyniki graficzne w pełni potwierdzają zalety proponowanej metody. Wyniki symulacji wykazały przewagę udoskonalonej metody analizy widmowej sygnałów radiowych; zaletę uzyskuje się poprzez wykorzystanie funkcji macierzy sumującej w procesie konwersji sygnałów. Zaproponowana udoskonalona metoda zwiększa o 12% dokładność wykrywania sygnałów tajnego pozyskiwania informacji.
