Research on Life Detection of Search Robot

When the coal mine accident happened, the gas and carbon monoxide concentration in the mine is higher, the environment is bad and the smoke is heavy, which brings great inconvenience to the rescue work after the disaster. In order to search for the surviving miners in time after the mine disaster, the life detection system of the search and rescue robot is studied in this paper. This paper first introduces the life detection techniques in the use of the tunnel after the disaster, the echo signal of through wall radar is theoretically deduced, and the Bessel function is used to process the echo signal. The basic frequency of breathing and heartbeat and the harmonic combination of the two are simulated
