Work aim - modelling and methods elaboration of ultrawideband sounding in order to disclose and recognise of geterogeneities in composed media. The results of the third stage of this research work are: -on the base of decision of the scattering problem of electromagneytic field limitted in time and in space at models of media which have layered structure on dept and losses, weredone the following conclusions of domaince of material parameters of reflecting half-space on spatio-temporal characteristics of reflected field. An effect of laying surface on wave ray propagation along her was studied and recommendations to measure device were defined: -on analysis of reflected field of impulsive wave bunch from half-space with losses are done the recommendations for undersurface sounding; -a model which permit to recognise complex object s was developed; - for experimental installation is got a summary impulsive signal from two generators of short impulses in direction of supervision attached to raised power of taken signal -1,5 kWt.
