1. A threat object map system comprising: a first sensor configured to acquire a first set of detection data associated with a plurality of objects within an environment, the first set of detection data including a first set of spatial coordinates; a second sensor geographically remote from the first sensor and configured to acquire a second set of detection data associated with the plurality of objects, the second set of detection data including a second set of spatial coordinates; a threat object map creation module configured to: receive and store the first and second sets of detection data; determine a plurality of correlation maps between the first set of spatial coordinates and the second set of spatial coordinates based on a plurality of N+1 point subsets selected from each set of spatial coordinates; determine the mean sphericity for each corresponding plurality of four-point subsets in the plurality of correlation maps; and create a threat object map based on the correlation map having the greatest mean sphericity, wherein N is the number of independent correlatable dimensions in the threat object map.
