Passive encoding microwave transponder

摘要: A passive transponder which provides remote identification of objects including cargo and trailers, vehicles or a variety move through an interrogator beam. The is mounted onto the vehicle object at location to be identified. transmitted beam from directed transponder. Some beam's energy rectified used power digital electronic circuitry within generates signal with serially-coded waveform. This amplitude modulates harmonic generator in produces emits derived incident interrogator. readily identified by receiver tuned that signal. information decoded data processor provide desired number. An internal clock frequency generated as result beam, this determines read-out rate encoded field programmable read-only memory.
