Abstract :
Many of today´s radar systems rely on digital processing for pulse compression. The future of SAW LFM pulse compression systems depends on achieving at least comparable performances to all-digital solutions. SAW-based pulse compression systems can consume less power and have higher dynamic range than all-digital systems, properties important for portable and long-range radars. The future market for SAW dispersive devices depends on development of larger time-bandwidth (BT) product device structures. Currently a BT of 10,000 is achievable, with a goal of > 20,000 in a single SAW device.
