Firstly, some logical rules are introduced for ghost point s elimination, which reduce the computa tion complexity, and the Hough transform for passive sensor systems is derived. T hen, the measurements from sensors are fuzzily mapped into parameter space, and thefuzzy accumulator shows the possibility of existence of tracks. The gradient orientation is used for lower computational complexity. Finally, the detection result is ob tained by fuzzy reasoning. Experiment results show that the proposed method could i
