Abstract : A procedure is designed for the Automated Statistical Characterization and Partitioning of Environments (A'SCAPE). A'SCAPE uses two procedures to partition regions into homogeneous areas. These are: (1) a mapping procedure that uses image processing to separate regions; and (2) a statistical procedure that uses statistics to separate regions. A'SCAPE is able to process real data through its image processing, statistical algorithms, and expert system rules. A parametric technique developed by LeCadre for the detection of signals in the presence of clutter and additive noise was also studied. This technique assumes an AR(MA) model of the interference. The order of the model is first estimated, the AR parameters are estimated, and then a covariance matrix is derived.
