The phenomena of interaction of electromagnetic and acoustic waves on limits of the section of environments with different type of conductivity and creation on their basis of parametrical radioengineering systems for the solution of applied problems of remote monitoring of various objects, a ground-penetrating radar, a wireless communication with submersibles on big depths, control of protected passes in places of a congestion of people are considered. In particular the following applied directions of use are considered. Parametrical interaction of electromagnetic and acoustic waves on limit of the section "water - air" can be applied to the organization of the direct and return suited information transfers for communication with deep-sea submersibles at the expense of modulation of conductivity of sea water under the influence of an acoustic field. Theoretical justification of the yielded method and results of experimental researches on a laboratory tank with the added some salt water is given. Possibility of use of parametrical interaction for the solution of problems of detection of small metal subjects, including precious metals, and also the weapon in controllable passes is proved. The principle of selective action of pulse magnetic fields is put in a basis of a method on metal particles and their replacement from an inductor field under the influence of Lorentz's strengths. The parametrical method can be used in the field of a ground-penetrating radar for problems of remote detection of mine. It is shown that imposing of waves of the Rayleigh expands space of informative signs of objects of search. The parametrical radar method of remote diagnostics of objects of railway transport in the movement, consisting in extraction of information on defects of controllable object by registration of frequencies of its own mechanical fluctuations is considered. One of the perspective directions of creation of parametrical radioengineering systems in the field of remote monitoring of large engineering constructions is given. In particular, possibility of realization of high-precision control methods of mechanical shifts of dams of hydroelectric power station is considered. Questions of further researches of parametrical interaction of electromagnetic and acoustic fields for the solution of problems of geophysics on the basis of supervision of seismoelectric effects in rocks are in summary mentioned.
