Abstract: FIELD: radio engineering. SUBSTANCE: invention is related to radio engineering facilities testing functioning and parameters of complex radio electron systems and their component parts at all stages of their operational life cycle by provision of simulation of several distant radiation sources or signals reflected from various objects including those travelling in space, with superimposition of several signals one on another in time which makes it possible to create complex scenarios of changing radio electron situation or flow of signals across input of modelled or tested equipment which may have place during operation of systems but which will be difficult or impossible to reconstruct during full-scale tests. Invention can be used in various automated systems of control or physical and mathematical (semi-full scale) modelling of different radio electron systems and devices. For achievement of mentioned technical outcome proposed simulator has many channels and controlling computer with interface, former of grid of reference frequency and adding unit. Each simulation channel includes digital frequency synthesizer, unit controlling setting of subranges, unit controlling signal spectrum, unit controlling signal power, decoder of channel number, master generator, frequency converter, first and second modulators and output attenuator. Mentioned above units included in simulation channel are intercoupled and connected to controlling computer. Former of reference frequencies is coupled to all simulation channels and to computer. Adding unit combines signals from outputs of output attenuators of simulation channels. Formation of signals of flow with their superimposition in time occurs in following way: portraits of signals are program-entered by setting of subrange, into on-line storage of control unit data on rate and intervals of reading of portraits from-on-line storage are entered into first and second modulators and into timers of control unit controlling setting of subranges, unit controlling signal spectrum and unit controlling signal power. Initial triggering of formation of signal flow is realized by feed of signal "synchronization" either into all channels simultaneously or into each channel separately in agreement with program which determines superimposition of signals. Reference frequencies from former of reference frequencies determine subranges of signals which spectrum is formed in proper digital frequency synthesizers with amplitude parameters preset by second modulators depending on data read from on-line storage of unit controlling setting of subranges of each channel and coming to commutator of reference frequencies and to commutator of frequency converters of each channel. EFFECT: creation of complex scenarios of changing radio electron situation, expanded application field. 9 cl
