Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

The paper deals with the method for detection of signals of ultrasonic nondestructive testing against the background of Gaussian noise. The method is based on analysis of circular dispersion, which is determined by phase characteristic of the studied signal, and does not require a priori information on the parameters of the model of ultrasonic nondestructive testing signal. Results of modeling the process of detection of signals of ultrasonic nondestructive testing against the noise background are given. 11 References, 4 Figures.
