Abstract
A surface wave phase correlator comprises a pair of substantially identical launch and receiving filter electrode patterns disposed on a common piezoelectric substrate. The correlator is employed with receiving and processing circuitry in a monopulse radar system to provide relative phase information for target calculations by a digital processor. Fast rise and fall times for the correlator output signals enable rapid digital processing of incoming target signals.
