1. A ground-based method of determining the spatial statistics of fragmented and spatially variably dispersed objects in a transmissive medium, said method including:

  • generating a plurality of pulsed beams of laser energy, said beams having selectively variable width and shape;

    selectively varying the width and shape of said beams directing said beams toward the dispersed objects;

    measuring the time and/or phase and intensity of signals returned by the dispersed objects, and calculating the apparent reflectance of the dispersed objects as a function of the range of the dispersed objects for each beam width and beam shape.
