Study of SAW pulse compression using 5*5 Barker codes with quadraphase IDT geometries
A theoretical and experimental study of pulse expansion and compression is reported for a 100-MHz SAW (surface acoustic wave) quadraphase code generator with 1250 IDT (interdigital transducer) fingers on ST-quartz as derived from a combined 5*5 Barker sequence. Techniques are also examined for increasing the peak-to-sidelobe ratio of the compressed pulse, using a series SAW suppression filter whose IDT apodization is derived from the inverse spectral ripple factor of the combined Barker code.<>
