DEVICE FOR FINDING NOISE-LIKE SIGNALS Russian patent published in 2006 - IPC H04L7/02 

FIELD: engineering of devices for finding, recognizing and receiving complex noise-like signals, possible use for finding complex noise-like signals in radiolocation, telemetric and communication systems.

SUBSTANCE: device additionally includes device for dividing in two, clock input of which is connected to output of pulse counter, input of which is connected to output of first key, while output of device for dividing in two is connected to controlling inputs of controllable key of threshold blocks and generator of time ranges, to second input of controllable key. Whole signal finding process is divided onto three cycles: in the first cycle fast scanning of signal indeterminacy area is performed and selection of three supporting signal delays is performed, which provide for maximal correlative response, at second cycle two-staged searching for signal among selected delays is performed, and at third cycle two-staged searching for signal is performed by stepwise checking of all signal delays.

EFFECT: decreased searching time with simultaneous simplification of device.
