New Method of Radio Detection and Location for Shallow Geophysics

Characteristics of subsurface objects search when solving the problems of shallow geophysics were considered. Amplification of nonlinear reflective properties of a heterogeneous physical object is possible by using parametric actions caused by different excitation physical fields, however, such fields should be chosen, whose specific losses are minimal in the process of going through the concealment environment layer. The new method of non-linear parametric radio detection and location was justified; the method consists in simultaneous supply of alternating voltage and bias voltage to the vibrator antenna, and this alternating voltage creates an exploratory electrical field while the bias voltage creates excitation constant electric field. As a result, due to resonance generation of bound magnetoelastic waves, different additional nonlinear waves are excited in the object including periodic nonlinear waves.
