In article discussed 4 aspects of signal reception such as information, power, time, space. The main point in the information aspect is the possibility to determine whether the received signal belongs of special radio-technical aids (SRTA), according to the availability of relevant content in the received message. The article gives examples of automated complexes and scanners and field indicators, realizing the phenomenon of "acoustic tie". It is noted that the presence of demodulation variants is not necessary for efficient signal detection SRTA. In general, it is proposed to represent a signal from the SRTA as a signal with a random basis in the time and frequency domain without taking into account the method of its generation. The fast signal detection parameters are specified when using tuning receivers [1]. The article justifies the influence of the energy aspect to solve the problem of detecting signals from the SRTA. The problem with artificial application of restrictions to limit values of SRTA parameters is also considered. Disclosed is a method of solving said problem. In the article the general scheme of tacit information control is executed. The article also provides conditions for the possibility of effective detection of a signal with unknown properties. The inventors justify the use of the radio emission of SRTA transmitters as an active feature, which can be optimized by the structure of searchers depending on the model of the detected signal, as well as depending on the conditions of the control point. You have identified factors that allow you to optimize your search engines.
