Abstract :
An acoustic surface-wave device capable of both the generation and compression of a linear FM waveform has been developed. The device has a synchronous frequency of 400 MHz, a dispersive bandwidth of 80 MHz, and achieved a pulse compression ratio of 25:1. The uncompressed pulsewidth is 0.5 /spl mu/s.
