SPACE-TIME CORRELATOR Russian patent published in 1999 - IPC

FIELD: signal processing in radio and radar systems. SUBSTANCE: correlator that has n adjustable amplifiers, n mixers, set of phase shifters, frequency changer, and integrator is provided, in addition, with n dispersed phase shifters and set of adders whose output is connected to second input of frequency changer; nth group of inputs of set of adders, m inputs per group where m is number of spectrum intervals of broad-band signal, is connected to respective outputs of i-th dispersed phase shifters whose inputs are connected to outputs of respective i-th mixers. EFFECT: improved signal-to-noise ratio at correlator output when processing broad-band signals. 3 cl, 4 dwg
