Modem radio engineering means (RTS) use difficult types of signals with intra pulse frequency and phase modulation (a WC and FM), with reorganization from an impulse to an impulse of the bearing frequency, duration and following intervals that significantly complicates their detection by means of radio engineering monitoring (RTM) in the conditions of a saturated radio-electronic situation (REO). For division of an entrance stream of signals according to their belonging to concrete RTS, during RTM realize monopulse measurement of parameters as a result of which receive descriptions of impulses, and then, on the basis of their analysis form descriptions of radiations. The algorithm of processing of signals of means of the radio engineering monitoring is presented in article, providing high precision and reliability of results at low ratios signal/noise. This algorithm allows to find continuous and quasicontinuous radiations with amplitude modulation, with linear and nonlinear a WC, with phase coding and to determine the following parameters: central frequency; arrival time; amplitude; duration (at the level of 0,5 from amplitude); existence of signs of ChM+, WC-LChM, NChM, FM, ChK; size of deviation of frequency. For check of operability of algorithm the diagram of the experimental installation and a graphics of a mean squared deviation of the measured values is provided. Conclusions are drawn on efficiency of algorithm on the basis of the obtained experimental data. Its advantages are also specified.
