The article examines possibilities of increasing of receiver sensitiveness of signal intelligence station by means of using of aerials with signal processing. It researches operation of SIGINT stations in complex signal environment, where undesired (spurious) signals influence on lateral directional lobes and reduce a ratio signal oise on the entrance of receiver. It proposes to set off the effect of spurious signals by means of controlled dips in the antenna diagram in direction of their arrival, as result the ratio signal oise on the entrance of receiver will be higher than with use of conventional aerial.
Keywords: aerials with signal processing, receiver sensitiveness, ratio signal oise, spurious signal, array, dip in the antenna diagram
