PERIODIC PULSED SIGNAL PACKET SELECTOR/DETECTOR Russian patent published in 2014 - IPC G01S7/36 

FIELD: physics, navigation.

SUBSTANCE: invention relates to radar engineering. The result is achieved due to that the selector/detector comprises a signal conditioner, a first delay line for delaying by the signal repetition period, a first coincidence circuit, a second delay line for delaying by the signal repetition period, a second coincidence circuit, as well as n additional transmission gate circuits, in each of which the signal input is connected to the first control input through a time shift element, and second control inputs of all gate circuits are connected to the output of the first coincidence circuit through series-connected first blanking circuit and gate circuit, the first control input of which is connected through a second blanking circuit to the output of the second delay line, and the second control input is connected to the output of the second coincidence circuit, the inhibit input of the first blanking circuit is connected to the output of the second coincidence circuit, the inhibit input of the second blanking circuit is connected to the output of the signal conditioner.

EFFECT: high noise immunity.
