ABSTRACT:
Count rate outputs of a probe-based radiation detection system are stabilized through the utilization of a dynamic window-based count analysis. Circular memory is utilized to record a sequence of segment count values. These values then are accessed and updated with respect to short scan intervals. The memory segments then are employed to develop a count sum over a count collection interval. That count sum is employed with algorithms adjusting the upper and lower edges of the dynamic window. A reported mean value, computed from the window upper edge or window lower edge, is utilized for creating a variable pitch output or for driving a bar graph. Background count and target count intervals are adjusted utilizing a data point predictive technique in combination with upper and lower time bounds.
