FIELD: radio communications.
SUBSTANCE: method includes emission of packet of M radio pulses, each on own frequency, different from frequency of adjacent radio pulse for frequency Δf. radio signals reflected from radio-contrast objects, which amplify and digitize, are received, while frequency of discretization for analog-digital conversion is set equal to Fadc=MΔf, to form M·K amplitudes of received radio signals, which are subjected to amplitude weighing operations and discontinuous Fourier transformation for M points. Resulting signals are compressed in M times compared to received ones.
EFFECT: higher efficiency, broader functional capabilities.
