Available Online 13 Dec 2010. To be published.
The article addresses the important for homeland security
possibility of robust detection of geometrically small, low
emission sources on a significantly stronger background. A
technique of detecting such sources using Compton type cameras is
developed and studied analytically and numerically, which is shown
to have high sensitivity and specificity and also allows to assign
confidence probabilities of the detection. The 2D case is
considered in detail.
