Abstract
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.
