摘要： Provided is a method for measuring inverse scattering wave, which includes installing a scattering object which is a test object in a coupler, feeding an electrical signal to an input terminal of the coupler, terminating an output terminal and an isolation terminal of the coupler so that the electrical signal scattered by colliding with the scattering object is transmitted to a coupling terminal of the coupler, and measuring intensity of the electrical signal transmitted to the coupling terminal. In addition, provided is an apparatus for identifying an inferior Radio Frequency IDentification (RFID) transponder and an inferior RFID reader by using the method for measuring the inverse scattering wave. Accordingly, the installation cost thereof is reduced. Furthermore, the facilities for the measurement can be installed in a narrow space, and the measurement can be done regardless of an external electromagnetic wave environment. Moreover, the apparatus for identifying the inferior RFID transponder and reader is installed on a production line, thereby removing the inferior RFID transponder and reader directly from the production line during the mass production.
