1. In an antenna having at least two elements, an apparatus for minimizing antenna:

  • backside signal response and ambiguity, comprising;

    a means for causing a phase difference having a plurality of outputs;

    a signal path connecting each of said at least two elements to a corresponding output of said means for causing a phase difference;

    a means for causing a variable time delay disposed in at least one said signal path;

    a processor; and

    a software program;

    said software program comprising computer implementable instructions capable of being executed in said processor wherein, when executed, causes said processor to control said means for causing a variable time delay so as tocause a null to be positioned in the antenna pattern of said antenna in the direction of an undesired received signal; and

    dither the position of said null.
