| Popis: | We study the performance of the sliced orthogonal nonlinear generalized (SONG) correlation for images degraded by clutter and nonoverlapping background noise. We present experiments on the optical implementation of the SONG correlation obtained by means of a joint transform correlator. Nonoverlapping noise does not contribute to the SONG correlation, and the SONG auto-correlation peak is insensitive to changes of background patterns around the target and experiments show that this is not the case for other methods. |
