Abstract
The correlator comprises a piezo-electric substrate on the ends of which there are arranged two transducers supplied with two electrical signals and emitting two contra-propagating surface waves. The correlator furthermore comprises m processing channels supplied with electrical signals induced by the surface waves at m 'points' on the substrate which are distributed in the direction of propagation of the waves. Each channel comprises a non-linear device and an integrator furnishing a sample of the correlation function of the two signals.
