Abstract

PURPOSE:To obtain real-time high-accuracy distance information by replacing station discrimination pulse with the response pulse corresponding to the interrogation pulse from an interrogator on a machine when the interrogation pulse is higher than fixed in advance. CONSTITUTION:Interrogation signal is captured by an antenna 21, inputted to a receiver 23 via a duplexer 22 and fed to a decoder 24. A decoder 24 detects only the pair pulse in video signal and feeds the pulse to a priority gate 27. The gate 27 gives priority in the outputting thereof to the response pulse corresponding to the interrogation pulse when the interrogation pulse is higher than fixed in advance. The output response pulse is transmitted from an antenna 21 via a coder 29, a transmitter 30 and a duplexer 22.
