Abstract
SAW dispersive delay lines are used for the generation and compression of chirp signals in modern radar systems. The influence of the passband-time duration (BT) product of the chirp signal on the sidelobe level of the compressed signal is presented. By using the best method for designing a periodical dispersive transducer two filters, middleband and wideband, can be used. Theoretical and experimental results of dispersive filters are presented. These techniques are used to design 10 /spl mu/s and 16 /spl mu/s dispersive delay lines, with up to a 100% passband, on quartz and lithium niobate substrates.
