Summary:1. Field of Invention A fuzzy controller () for use in target detection systems. The fuzzy controller () includes a first circuit () for determining a number of false alarms in a frame of data. A second circuit () determines a desired number of false alarms for the frame of data. A third circuit () computes a threshold multiplier factor based on the number of false alarms, the desired number of false alarms, and one or more fuzzy rules. In a specific embodiment, the first circuit () includes a target detection system for providing addresses of pixels whose values are within a predetermined range relative to a detection threshold. The second circuit () includes an input device () for accepting the desired number of false alarms as input to the fuzzy controller (). The third circuit () includes a fuzzifier input calculation circuit () that computes a fuzzifier input value based on the number of false alarms detected in a frame and the desired number of false alarms.
