Abstract:
1. An obstacle detecting system having leakage coaxial cables laid at both the sides of an obstacle monitoring district; an obstacle detecting device for (i) emitting electrical waves from one of the leakage coaxial cables laid at one side to the other leakage coaxial cable and (ii) detecting an obstacle in the obstacle monitoring district on the basis of the electrical waves incident to the other leakage coaxial cable; an electrical wave transmitting unit for transmitting the electrical waves to the one leakage coaxial cable in the obstacle detecting device; an electrical wave receiving unit for receiving the electrical waves incident to the other leakage coaxial cable; and a connecting unit for connecting the electrical wave transmitting unit and the electrical wave receiving unit, wherein the obstacle detecting device (i) detects an output level of the electrical wave transmitting unit on a basis of the electrical wave passing through the connecting unit and (ii) corrects the output of the electrical wave transmitting unit.
