Movable body detecting/notifying system |
摘要 |
To provide a movable body detecting/notifying system that is capable of determining and reporting whether another movable body exists behind an obstruction or at a position that can be verified by the sense of sight. A movable body detecting/notifying system allows a detecting movable body to detect and report a detected movable body by using electromagnetic wave communication. The detected movable body transmits a large-wavelength electromagnetic wave easily diffractable by an obstruction as well as a small-wavelength electromagnetic wave not easily diffractable by an obstruction at the same time. The detecting movable body generates a notice for reception of only the large-wavelength electromagnetic wave without the small-wavelength electromagnetic wave or a notice for reception of both the large-wavelength and small-wavelength electromagnetic waves different from the notice for reception of only the large-wavelength electromagnetic wave.
