FIELD: radio engineering; radiolocation. ^ SUBSTANCE: unit is used for simulating as simple single-point and complex multi-point moving objects within wide frequency band for several radiolocation installations simultaneously. Unit has receiving and transmitting aerials, n-channel frequency-selective splitter, n-channel frequency channel adder, n single-band balance modulators and n units for reproducing signal spectrum of radiolocation installation reflected from real moving objects. Unit provides receiving of signals of radiolocation installation, selecting along frequency channels inside any of which the single-band modulation is carried out by signals of Doppler frequency spectrum, which store at reproduction Doppler frequency spectrum being individual for any frequency channel. Irradiation of formed signals is provided backwards as well. ^ EFFECT: improved efficiency of simulation. ^ 1 dwg |
