<p>PURPOSE:To obtain the response data having the high reliability by selecting the data having the max. reception level from the equal data in an equal distance among the responce data of a transponder and selecting the equal data having the min. distance from among the data having different distance. CONSTITUTION:A distance data generating circuit 12 sends the distance data (d) having a trigger signal (c) as standard into a decoding circuit 11. A timing signal generating circuit 14 receives the direction data (b), and generates the timing signals (i) and (j). The circuit 11 receives the reception signal (a) and the data (b) and (d) supplied from a transbonder, and the data (f) and the position data (e) are sent into a circuit 12. In the circuit 13, memory is cleared by the signal (i) supplied from a circuit 14, and the data (f) and (e) supplied from the circuit 11 are received, and the memory data which is supplied from a pseudo responce removing part 15 and corresponds to the address data G is read out, and the data (h) sent into the removal part 15. In the removal part 15, the reception level of the same response data in the equal distance is max., and the data (k) having the min. distance is selected from among the data having different distance.</p> |
