GENERATOR OF SIGNAL FOR TURNING JAMMING ON Russian patent published in 1998 - IPC

FIELD: tracing radar equipment. SUBSTANCE: device generates jamming signal when subjected to pulse sequences or pulse bursts which period is not greater than threshold with total duration of probing pulses not less than given threshold. Device has first resistive voltage divider, first pulse stretcher, integrating RC circuit, first p-n-p transistor, which base is connected to output of first resistor voltage divider, and emitter serves as input of generator of signal for switching jamming station on. Goal of invention is achieved by introduced second p-n-p transistor, second resistive voltage divider, second pulse stretcher, emitter of second p-n-p transistor is connected to output of integrating RC circuit, base is connected to output of second resistive divider, collector to input of second pulse stretcher, which output serves as output of generator of signal for switching jamming station on. EFFECT: possibility to store ON condition for specified period, independent setting of threshold level of burst period, total duration of probing pulses necessary for turning on, as well as time for storing ON state. 3 dwg
