Method for sub-surface radar sounding is realized through emitting to interior of Earth of nano-second pulses and reception of signals reflected from under-surface objects by means of transmission and receiving antennas as mirror reflectors – paraboloids of revolution that are filled with foamed dielectric ferrite-perofskite composite and closed in opening with plates of composite with wave resistance that is equal to wave resistance of foamed composite, and by means of emitter with winding and with ferrite-perofskite core. Before emitting high voltage is collected in capacitor of transmitter, with powerful excitation of emitter of emitting antenna at discharge of capacitor during several nano-seconds through key element. One observes structure of under-surface medium with determination of depth of bedding of under-surface objects at obtaining signals from emitter of receiving antenna through determination of delay of reflected signals with respect to sounding pulse. To increase depth of sounding of under-surface objects with continuous form and to increase accuracy of determination of direction to those objects sounding pulses are directed and received by means of short-focus mirror reflectors-paraboloids of revolution and emitters of those with winding as undirected cylindrical two-step, respective left and right spiral of cooper wire, placed in focuses of transmitting and receiving antennae, respectively. |
