| 摘要 |
The invention relates to means of contact-less search for present heterogeneities through measurement of amplitude and phase of electromagnetic wave caused by heterogeneities of massif being studied, for search of liquid, gaseous and solid minerals in case of implementation of measurements in points separated in space. System for search of heterogeneities in earth’s crust includes emitting and measuring antennae, transformer, block for formation of two signals with constant frequency difference that includes generator of support frequency, power amplifier, selective amplifier. Additionally there are included transmission and reception modules, at that first section of block for formation of two signals with constant frequency difference is placed in transmission module, and second part – in receiving one. The first part includes first frequency synthesizer, and second part has second frequency synthesizer, besides that the system additionally includes first GPS module, first micro-controller, second power amplifier, emitting antenna of support signal, receiving antenna of support signal, preliminary amplifier, analog-digital transformer, frequency divider, low frequency filter, synchronous amplitude detector, second micro-controller, second GPS module and personal computer. Application of the invention increases accuracy of measurements, simplifies hardware realization of the device, decreases overall dimensions and power consumption. |
