Claim:
A process for analyzing radar scattering data from an area-of-interest comprising: receiving radar scattering data from the area-of-interest, the area-of-interest includes at least two scattering points; identifying the radar scattering data as containing multiple-bounce information resulting from reflection off of the at least two scattering points; imaging the area-of-interest using the multiple-bounce information; and separating the radar scattering data according to the identifying the radar scattering data, wherein separating the radar scattering data comprises: reconstructing the at least two scattering points according to the identifying the radar scattering data, wherein the reconstructing the at least two scattering points comprises: reconstructing a multiple bounce reflectivity function (â€œMBRFâ€)Æ’(x,y,Î³) for each of the at least two scattering points based on measured phase history data as described according to the equation G â¡ ( Î¾ , â¢ Î¸ ) â‰¡ âˆ« âˆž âˆž â¢ â¢ â…† x â¢ âˆ« âˆž âˆž â¢ â¢ â…† y â¢ âˆ« âˆž âˆž â¢ â¢ â…† Î³ â¢ â¢ f â¡ ( x , y , Î³ ) â¢ exp â¡ ( - j2Ï€ â¡ [ x â¢ â¢ cos â¡ ( Î¸ ) + y â¢ â¢ sin â¡ ( Î¸ ) + Î³ ] â¢ Î¾ ) , wherein Î¾ represents spatial frequency and Î¸ represents measurement angle.
