Earth probing radar system |
摘要 |
A ground probing radar method and apparatus which is effective to view the earth in advance of coal mining activity provides visual display of a coal seam and particular discontinuities that may lie therein. The system operates in the frequency range of 10 Megahertz to 5 Gigahertz. The received electromagnetic energy is amplified, sampled and band pass filtered with subsequent time gain amplification. A time analog return signal may be viewed directly and/or the return signal may be digitally processed to enable further signal refinement. A control microprocessor is utilized for both tape record control and digital signal processing, and the processor includes the capability for compositing and/or stacking of common source point data for output record and display.
