Abstract :
A symmetric V-shaped frequency-modulation chirp is used to demonstrate pulse compression of variable-bandwidth signals centred at 1.3 GHz. The compression device is based upon the nonlinearity in a lithium-niobate longitudinal-wave acoustic delay line. Uniformity of the interaction region is achieved so that the convolution is not spatially weighted.
