Annotations languages:

In the article formulas, allowing to estimate potential exactness measurings of delay of useful signal, are got on a background preventing. Formulas are specified применительно for signals with the rectangular and скругленной form of spectrum of sounding signal. Calculations are conducted and the graphs are built, allowing to estimate potential exactness measurings of delay of useful signal on a background preventing at equal amplitude of preventing and useful signal, and also as it applies to a case, when amplitude of preventing signal on an order less useful. The difference of phases between useful and preventing signals here relied casual a size. A case is considered, when this difference of phases took on discrete values and case, when averaging was conducted on her.
Keywords: potential exactness, useful signal, preventing signal, correlation matrix, complex amplitude, casual parameters of signal
