Abstract
Formulation of the problem in general. The question of determination of the instantaneous significance of the radio emission sources’ carrier frequency in the conditions of high aprior uncertainty of signal parameters and the limited resource potential of radiomonitoring forces and means is an actual scientific and practical task. Analysis of recent researches and publications. An analysis of existing mathematical models describing the processes of determining the carrier frequency of radio emission sources has shown that they take into account only linear results of measurements. In modern conditions, the task of creating a new generation of informational-measuring technologies, methods, algorithms and procedures becomes a special urgency. Presenting the main material. For the mathematical formalization of the process and the development of a general procedure for determination of the instantaneous significance of the radio emission sources’ carrier frequency, it is advisable to use the method of maximum likelihood. Conclusion. The analytical approach, that is a mathematical formalization of physical processes which take place at determination of estimations of bearing frequency of radioemission sources during the radiomonitoring, is shown in the article. The got analytical expressions can be used for development of new and improvement of existent methods of instantaneous determination of bearing frequency of radioemission sources with further development of devices of their realization. The perspectives of future researches. Solving the problem of obtaining new analytical dependencies during the simulation of processes occurring in devices that carry out mono-pulse bearing of radioemission sources will become the research in the nearest future.
