摘要: An electronic system for the remote identification of objects such as livestock comprising a transponder (A-G) having a predetermined code stored therein positioned on the object to be identified, and an interrogator for remotely interrogating said transponder; the transponder has comparator means (18) for comparing the decoded VHF signal from the interrogator with a stored code wherein a valid comparison initiates the transmission of a return signal (f3) which actuates an automatic direction finder (ADF) in the interrogator.
