A method for detecting a single-circuit or two-circuit PARAMETRIC LENS

摘要

A method of detecting single-circuit or dual-circuit parametric scatterers, which consists in the fact that the search for the facility previously located Turbofan parametric diffuser parametric oscillation frequencies f1 and f2, with f1 + f2 = f, or a single-loop parametric diffuser 0,5f parametric frequency generation, the region of space which may be the search object is irradiated with the probing signal forming process in the nonlinear scattering from parametric diffuser sequence elnost packs narrowband coherent radio pulses scattered signal, with each packet corresponding to a codeword, and each radar pulse burst corresponds to a character of the selected coding law which is a binary sequence whose elements correspond to differing by π, the values ​​of phase high-frequency radio pulses, for this probe signal comprises sequence of rectangular packs narrowband coherent radio pulses of the pump signal with frequency vysokochastotnog filling f and τ, pulses furthermore probe signal comprises a sequence of narrowband coherent synchronizing RF pulse with a frequency of the high-frequency f1 and duration radio pulse τ1, wherein τ1 substantially less than τ, the phase of the high-frequency synchronizing radio pulse corresponds to the current ordinal symbol selected law manipulation and leading edge the clock pulse coincides with the leading edge of the pulse pump or ahead of it on time has not been exceeded
