Abstract: For the current exploration of coal mine safety and coal mining, we designed a Ground Penetrating Radar receiver system which could survey the coal seam thickness and other media around. After receiving signals by the aerial at the front end of the system, the low noise amplifier could be used to amplify the signals. Then high-speed sample would be taken to complete the data acquisition. The data processing could be finished in Altera’s FPGA development board Cyclone IV. LMS method in self-adaptive algorithm could be used. This receiver system can be applied in coal mine exploration area, the data of coal mining area can be obtained through advanced detection. In this way the safety of coal mining can be guaranteed and the production efficiency can be improved. for future advanced detection of coal mine has great actual application value.
