FIELD: measuring tools.
SUBSTANCE: device comprises a synchronizer (1), a modulator (2), a microwave generator (3), an antenna switch (4), an antenna-feeder device (5), a receiver (6), an indicator (7) and a block (8) for measurements of the refractive index of the atmosphere in the interests of radar. In this case, the block (8) for measuring the refractive index of the atmosphere for the purposes of radar comprises a frequency dispersion compensator (8.1), an analogue-to-digital converter (8.2), a Hilbert converter (8.3), a phase detector (8.4), a delay line (8.5), three adders (8.6, 8.7, 8.9), a subtractor (8.8) and a group velocity calculator (8.10).
EFFECT: measurement of the refractive index of the atmosphere.
