Abstract :
Develops methods for localizing particle sources using detector arrays. Projection-based arrays are used and general convex, cubical, and spherical surfaces are investigated. Lower bounds are computed on the mean-square angular error (MSAE) for these arrays. The authors propose an algorithm for direction finding with the cubical array and analyze its MSAE. Potential applications of the proposed methods include finding radiation sources, localizing weak light sources, studying the environment, and verifying compliance of nuclear nonproliferation treaties
