METHOD FOR SELECTION OF NON-LINEAR DIFFUSERS BY PHASE DEVIATION OF RESPONSE SIGNAL ON SOUNDING

摘要

A method for selection of non-linear diffusers by phase deviation of response signal on sounding includes emission of mono-harmonic or bi-harmonic sounding signal with modeled amplitude in direction towards non-linear diffuser, reception and registration of non-linear products as response signal. For identification of non-linear diffusers one uses the effect of phase deviation for non-linear products, multiple harmonics or combinatory frequencies, at variation by saw-tooth law or other one of the level of power of electromagnetic field formed by mono-harmonic or bi-harmonic sounding signal.
