  • Null pattern technique for reduction of an undesirable interfering signal
    Patent number: 4214244
    Abstract: A null pattern technique for reducing the effect of an undesired interfering signal in a data link channel, using an accepted monopulse tracking arrangement in a novel mode, such that the source of such interfering signal can be caused to be placed at the null of the antenna pattern used, thus greatly increasing the desired-signal-to-interfering-signal ratio without necessitating a physically large antenna.
