In photoelectric jamming system, the evaluation method of photoelectric jamming to detector plays an important role. Through analyzing the fuzzy factors which affect the efficiency of photoelectric jamming, the models of integrated fuzzy evaluation of photoelectric jamming are proposed, including degree of collimation model, energy density model, laser wavelength model, pulse width model, atmospheric condition model and surface quality model of photoelectric material. The fuzzy relation matrix could be calculated through degree of membership of single factor.Furthermore, the integrated fuzzy evaluation results of effectiveness of photoelectric jamming are induced. Also a calculation example is given. The result proves that the integrated fuzzy evaluation method of photoelectric jamming to detector is an effective way to carry out efficiency evaluation of photoelectric jamming.
