The basic theory of operation of ultra wideband radio identification systems is explained in this letter. An experimental setup based on an ultrawideband radar working as a reader is proposed to measure time-coded tags. A method based on the Continuous Wavelet Transform is developed in order to overcome detection problems associated to a low signal-to-noise ratio at the receiver. Experimental results obtained with the ultrawideband radar and using an ultrawideband antenna connected to a delay… CONTINUE READING
