Abstract
A moving body detection system for detecting moving bodies by transmitting and receiving signals between the moving bodies, each moving body transmits an ID code capable of identifying the moving body itself as a fixed output ID code signal for a fixed period. A detection side moving body receives the ID code signal for the same transmission period as the ID code signal based on changes in driving conditions, discriminates the received ID signal and gives an order of priority to each ID code based on the discrimination results, and transmits a detection signal with the ID code and the ID code of the detection side moving body itself added at prescribed time intervals in ID code order. A non-detection side moving body receives the detection signal, and transmits a response signal with its own ID code and the ID code of the detection side moving body added if the ID code added to the detection signal is the same as its own ID code. Furthermore, the detection side moving body receives the response signal and measures the distance to the non-detection side moving body having the same ID code as the response signal.
