摘要： PURPOSE: To reduce the cost by reducing external noise influence so as to attain high sensitivity, widening the interval between transmission and reception antennas and also simplifying the configuration of the equipment for discriminating a reception signal. CONSTITUTION: A question signal generated in a question signal generator 25 is modulated by spread spectrum based on the PN code of a PN code generator 24 and radiated from the transmission antenna 27 as radio wave. At the time of no resonant label 32, question radio wave 31 is received by the reception antenna 28. At the time of existing resonant label 32, question radio wave 31 and response radio wave 33 are received and reverse spread spectrum is executed through the use of a PN code being the same as that at the time of spread spectrum in a spread demodulator 29. At the time of question radio wave 31 and response radio wave 33, restoration is executed as the signal of an original narrow band by reverse spread spectrum. But, noise and other radio wave mixed during transmission are reversely scattered in a wide band so as to reduce an electric power level, an S/N is improved, detection sensitivity is considerably improved so that the interval of the transmission and reception antennas 27 and 28 can be widened.

CONSTITUTION: A question signal generated in a question signal generator 25 is modulated by spread spectrum based on the PN code of a PN code generator 24 and radiated from the transmission antenna 27 as radio wave. At the time of no resonant label 32, question radio wave 31 is not received by the reception antenna 28 since polarized wave surfaces between the transmission and reception antennas are orthogonal. At the time of existing resonant label 32, response radio wave 33 by resonance is received and reverse spread spectrum is executed through the use of a PN code being the same as that at the time of spread spectrum in a spread demodulator 29. Response radio wave wave 33 is restored as the signal of an oritinal narrow band by reverse spread spectrum, but, noise and other radio wave mixed during transmission are reversely scattered in a wide band so as to reduce an electric power level, an S/N is improved and detection sensitivity is considerably improved.

摘要： PURPOSE: To reduce the cost by reducing noise influence so as to attain high sensitivity, widening the interval between transmission and reception antennas and also simplifying the configuration of an equipment for discriminating a reception signal. CONSTITUTION: A question signal which matches with the resonance frequency of a resonant label 30 is transmitted from the question signal generator 26 of a transmitter 24 and question radio wave 29 is radiated to the air. At the time of no resonant label 30, the question signal 29 of vertical polarized wave is radiated from the transmission antenna 22 but question radio wave 29 is not received on a receiver 25 side since only horizontal polarized wave is received by the reception antenna 23. At the time of the resonant label 30, the polarized wave surface of the question signal 29 is rotated by resonating question radio wave 29 so as to be scattered and response radio wave 31 is transmitted. When the response radio wave 31 is received, the reception antenna 23 discriminates a signal level by the reception signal discriminator 27 of the receiver 25, an alarm driving signal is transmitted to an alarm generator 28 when the signal level is more than a fixed level and issues alarm sound.
