MATCHED FILTER Russian patent published in 1994 - IPC

FIELD: radio and instrumentation engineering. SUBSTANCE: simplification of design of filter is achieved by coherent storage of signal in monoperiodic structure of output electrode of delay line with subsequent narrow-band filtering of signal expanded to duration of N-fold radio pulse signal and by amplification of mixture of signal and noise ahead of mixer up to such level that inherent broadband noise of mixer can be disregarded when estimating resulting signal-to-noise ratio across output of delay line. EFFECT: simplified design. 1 dwg
