FIELD: radio engineering. ^ SUBSTANCE: jamming station includes receiving antenna, input switch, high-frequency amplifier (HFA), switch, splitter, band-pass filter, detectors, video amplifiers, control signal shapers, keys, decoder, adder, output HFA, gate signal generator, transmitting antenna, radar surveillance cycle duration measurement units, control and synchronisation unit, channel gates, threshold elements, keys, triggers with individual drive, differentiating circuits, diode limiters, biased multivibrators, triggers with controlled computing drive, time-interval counters, generation devices of PD (pulse doppler) radar presence bit in antenna directivity diagram (ADD) of JS and determination of the number of pulse repetition frequencies (PRF) used in it; device for determining the number of radiating radars in JS ADD; device for determining the number of radiating PD radars. Increase in JS (jamming station) efficiency by increasing its number of channels as per the number of suppressed PD radars of detection and tracking of trajectories is based on peculiarities of their functioning owing to creating discontinuous interference. ^ EFFECT: increasing efficiency of the jamming station by increasing its number of channels as per the number of suppressed pulse doppler radars of detection and tracking of trajectories. ^ 3 dwg |
