An alternative variant of radio-signals energy detection theory developed on the basis of M. Lomonosov energy conservation law and Bayes unconstrained optimization of statistical decisions is considered. Radio-signal energy detection implies search of a time interval where the total signal-and noise energy against average internal noise energy exceeds the detection threshold with the given qualitative measure. The methods of sequential and parallel radio-signals energy detection at radio frequency for the signals commensurable or lower than the level of radio-receiver internal noise when the influence of external active masking interference is not taken and taken into account are discussed.
