Abstract. Processing of signals from radio emission sources in airborne monostatic radio monitoring systems requires solving the problems of its identification and estimation of the state coordinates. The radio emission sources identification is understood as establishing a correspondence between separate signals detected by radio monitoring system and radio-emission source specimens. The estimation is understood as forming optimal estimates of the state coordinates of tracking radio-emission source. The algorithm of multitarget route tracking of radio-emission sources using monostatic air-borne radio monitoring system is developed in the article. Developed algorithm includes three stages: the formation of hypotheses about identification, estimation of the state coordinates of all objects for each hypothesis and the choice of the most plausible hypothesis. Radio monitoring systems specificity is that there is no possibility for directly measuring of radio emission source range. In this conditions methods of its indirect estimation based on angle measurements are used for estimation of state coordinates of the tracking objects. In the article an algorithm of estimation of the state coordinates of tracking objects was based on extended Kalman filter. Based on the simulation, the efficiency of the developed algorithms was investigated.

Key words: multitarget tracking, radio emission sources, radio monitoring system, angular position measurement, Kalman filter.
