RECIRCULATION ACCUMULATOR OF A STACK OF MUTUALLY COHERENT RADIO-IMPULSES Russian patent published in 2008 - IPC H03K5/19 

FIELD: radio engineering, possible use for finding a stack of mutually coherent impulses.

SUBSTANCE: device contains input block, connected to first input of adder. Second input of adder is connected to output of reverse communication amplifier. New feature is the introduction of compensating amplifier and band filter. Input of amplifier is connected to output of delay line, and output of amplifier is connected to input of band filter. Delay line consists of input, intermediate and output of inter-digital transformers on sound-conductive substrate. Duration of interaction of train of waves in output inter-digital transformer is selected to be several times or several dozen times greater than delay of signal between input and intermediate inter-digital transformers, output inter-digital transformer is made in form of continuous mono-periodical structure, matched with carrying frequency of received radio-impulses, and connected to input of compensating amplifier. Pass band in band filter is selected to be commensurable with reverse value of duration of radio-impulse signal generated in output inter-digital transformer.

EFFECT: increased detection capability of accumulator without worsening of its stability.
