RADIO SIGNALS BICHANNEL IMITATOR Russian patent published in 2007 - IPC G01S7/40 

FIELD: the invention refers to the field of radio technique particularly to instruments of imitation of radio signal of the sources of radio emission.

SUBSTANCE: it may be used at developing and testing of systems and means of radio communication, radio monitoring, at development of solution of applications of position finding according to sensed direct and repeated signals, and also at training operators of indicated systems. Availability of the second imitation channel and possibility of installation of prescribed value of delay between the chosen signals of the both channels allow to make imitation of receiving signals incoming by different paths of propagation. A radio signal imitator has a synchronous signal generator of the reference frequency(1), controlled frequency dividers(2,13,15), a control arrangement(3), communication equipment(4), a memory unit(5), digital-analog converters(6,16),a data reading device(7,14),a data recorder(8), a flow control data unit(9),band filters(10,17), a frequencies transfer device(11,18), an analog-to-digital converter(12), a delay forming unit(19), level regulating units(20,21), a switch(22), an adder(23), main memory units(24,25).

EFFECT: provides imitation of complex signal situation on a receiving radio station.
