Abstract: Mean nuclear backgrounds are large, but are arguably amenable to
frame-to-frame subtraction. Striated backgrounds on the sensors for defensive
interceptors could, however, cause clutter leak-through, which could make
detection and track difficult. Nominal motions and backgrounds give signal to
clutter ratios too low to be useful. Clutter leakage due to line-of-sight drift
can be reduced by stabilizing the line of sight around the background clutter
itself. Current interceptors have detector arrays large enough for operation
independent of nuclear backgrounds in their fields of view.
