1. A system for locating an emitter emitting a radio frequency signal in a radio field, the system comprising:

  • a movable receiver capable of detecting and recording an amplitude of the radio frequency signal from a plurality of locations within radio field;

    means for generating a grid of points representing an area of interest within the radio field;

    means for calculating the distance between each of the grid points and the plurality of receiver locations;

    means for calculating an expected signal strength for each of the grid points based on an assumed power and radiation efficiency of the emitter; and

    means for generating a prediction of the location of the emitter.
