DEVICE FOR FINDING BROADBAND SIGNALS Russian patent published in 2007 - IPC H04L7/02 

FIELD: radio engineering, possible use for building radio communication, radio navigation and control systems which use broadband signals.

SUBSTANCE: in broadband signal finding device, which contains linear part, clock impulse generator, two detectors, two threshold comparison blocks, NOT element, AND element, n/2 inverters, second adder, synchronized filter containing a preliminary filter, delay line, n attenuators, n phase shifters and first adder, block for analyzing interference situation of natural background, OR element, adjustable generator, key and counter of fixed numbers, output of linear part is connected to input of block for analyzing interference situation of natural background, output of which is connected to first input of OR element and input for zeroing the counter of fixed numbers, input and controlling input of key are connected respectively to output of clock impulse generator and to output of binary counter, input of which is connected to output of AND element, output of fixed number counter is connected to second input of OR element, and output of adjustable generator is connected to linear part for generating its adjustment frequency.

EFFECT: reduced broadband signal finding time under conditions of effect of high level interferences.
