This paper analyzes the advanced signal processing method of atmospheric space radar and the sampling, filtering and analysis of gas detection signals in coal mine. The feasibility and technical realization of gas distribution are obtained. By analyzing the obtained gas data and inferring the coal mine The geologic structure distribution of gas provides the basis for coalmine safety assessment and prediction. With the help of the gas detection data of the geologic radar roadway, the simulation system is established and modified, and the computer signal simulation is carried out by matlab to improve the signal processing method of the geologic radar.
