NOISE-LIKE SIGNAL SEARCH DEVICE Russian patent published in 2006 - IPC H04L7/00 H04B1/10 

FIELD: radio communications; radar, radio navigation, and communication systems using noise-like signals at carrier instability.

SUBSTANCE: newly introduced in device are exponential-characteristic n-channel nonlinear elements, n-input adder, threshold element, threshold shaper, and gating element; outputs of amplitude detectors of each correlating channel are connected to inputs of nonlinear elements whose outputs are connected to respective inputs of adder; output of the latter is connected to first input of threshold system and to input of threshold shaping circuit whose output is connected to second input of threshold circuit; output of the latter is connected to first input of gating circuit whose second input is connected to sixth output of synchronizing unit.

EFFECT: enhanced noise immunity in noise-like signal detection.
