Abstract
A responder that receives an interrogation wave from an interrogator and transmits a response wave to the interrogator, includes at least one antenna receiving the interrogation wave, a time-series information converter measuring a quadrature phase amplitude of the interrogation wave received by the antenna and converting the quadrature phase amplitude into time-series information, a memory storing the time-series information, and a transmission controller controlling to transmit the response wave from the antenna based on the time-series information stored in the memory, wherein the transmission controller reads out the time-series information in an order reverse to an order of the storage in the memory and generates the response wave.

A responder that receives an interrogation wave from an interrogator and transmits a response wave to the interrogator, comprising:
- at least one antenna receiving the interrogation wave;
- a time-series information converter measuring a quadrature phase amplitude of the interrogation wave received by the at least one antenna and converting the quadrature phase amplitude into time-series information;
- a memory storing the time-series information;
- and
- a transmission controller controlling to transmit the response wave from the at least one antenna based on the time-series information stored in the memory, wherein
- the transmission controller reads out the time-series information in an order reverse to an order of the storage in the memory and generates the response wave.
