ADAPTIVE DIGITAL RECIRCULATING DEVICE Russian patent published in 2007 - IPC G01S7/36 

FIELD: radio engineering, possible use for accumulating signals in concealed radiolocation complexes with impulse-Doppler radiolocation stations used as supporting stations, under conditions of unknown or changing repeat period of probing signals.

SUBSTANCE: known recirculating device contains serially connected adder, device for forming check connection signals, random-access memory. In accordance to invention, following devices are introduced: repeat period meter, decoder, a set of keys, number of which depends on changing range of repeat period and number of shift registers of random-access memory. The output of the repeat period meter is connected to decoder, from where information is sent to controlling inputs of keys, at information inputs of which signals from shift registers of random-access memory are received. Outputs of keys, depending on signal from decoder, are connected to second input of arithmetic device adder.

EFFECT: introduction of new elements and connections into suggested device allows expanded functional capabilities of digital recirculating device, providing for its adaptation to change of repeat period of probing signals of opponent's radiolocation stations.
