Moving body discriminator.

摘要

A moving body discriminator has a data processor (100) for outputting a communication command; a plurality of controllers (101-10N) each connected to the data processor (100) and inputting the communication command outputted from the data processor (100) and outputting a predetermined instruction; a plurality of question antennas (111-11N) connected and corresponding to the plural controllers (101-10N) and inputting and outputting the predetermined instruction outputted from each of the corresponding controllers (101-10N); and a responder (120) for inputting the predetermined instruction by spatial transmission and outputting a specified signal to a question antenna outputting the predetermined instruction. The plural controllers (101-10N) control operations of the plural question antennas (111-11N) such that the plural controllers (101-10N) sequentially operate the plural question antennas (111-11N) in a predetermined order to communicate with the responder (120).
