1. A direction-finding method comprising the steps of:

  • establishing a cross-over position point, said cross-over point defined as the intersection between LOBs generated by at least two receiving incident electronic signal;

    relocating one said receiver to a new receiver spacial location;

    said receiver at said new receiver position receiving a transmission from a transmitter at a transmitter position;

    determining a real-time line of bearing from said receiver at said new receiver position to said transmitter;

    generating a connecting vector from said real-time line of bearing to said cross-over position point; and

    identifying a real-time position of said transmitter along said connecting vector;

    displaying said real-time position on a user display panel; and

    generating and displaying probability overlay map responsive to said real-time position and said quality factor on said user display panel.
