Abstract
A moving object discriminating system is arranged so that a signal transmitted from an interrogator is received by a responder where the signal received is processed at a control circuit, the processed signal is phase-modified by own stored data of the responder and returned to the interrogator as an answer signal, and the interrogator discriminates the moving object as based on the answer signal. The responder is thereby sufficiently minimized in size for achieving as improved mountability of the responder with respect to the moving object to be discriminated.
