SAW dispersive delay lines in radar signal processing
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.
