Automatic Target Recognition (ATR) is difficult in general, but especially with RADAR. However, the problem can be greatly simplified by using the 3-D reconstruction techniques presented at SPIE[Stuff] the previous 2 years. Now, instead of matching seemingly random signals in 1-D or 2-D, one must match scattering centers in 3-D. This method tracks scattering centers through an image collection sequence that would typically be used for SAR image formation. A major difference is that this approach naturally allows object motion (in fact the more the object moves, the better) and the resulting 'image' is a 3-D set of scattering centers scattering centers directly from synthetic data to build a database in anticipation of comparing the relative separability of these reconstructed scattering centers against more traditional approaches for doing ATR.
