PROBLEM TO BE SOLVED: To provide a low-cost reflector, radar apparatus and radar system capable of detecting identification information (ID information) of a target from a reflected wave of a transmission signal, with a simple structure.SOLUTION: A reflector 10 has reflecting plates 11, 12 and a power section 13. The reflecting plate 12 is formed in a total reflection state in which an incident wave is reflected by the entire surface of the plate, whereas the reflecting plate 11 is formed such that a part of its surface reflects an incident wave but the remaining portion transmits an incident wave. When a wavelength of a transmission signal is λ, a gap d between the reflecting plate 11 and the reflecting plate 12 is alternately changed at a natural period between λ/4 and 0 by the power section 13. |
