Abstract

To provide a moving body detection system capable of reliably receiving response signals and discerning the arrangement of opposing moving bodies. A moving body detection system for transmitting and receiving signals in such a manner that moving bodies can detect each other, wherein each moving body transmits an ID code for identifying the moving body itself and giving a priority to the moving body as an ID code signal of a fixed time period, each moving body receives said ID code signals of other moving bodies, each moving body receiving an ID code signal makes a determination as to whether or not a neighboring upper order moving body of a higher order than itself is present within a prescribed distance and each moving body determining the presence of a neighboring upper order moving body receives a detection signal transmitted from a detection side moving body and transmits a response signal only when the neighboring upper order moving body is determined not to be present.
