Taking into account various impacting factors,a fuzzy evaluation method is presented in this paper to assess the jamming effect of CCD array detector by pulse laser.The implemental process of the fuzzy evaluation method is introduced.At the same time,the degree of collimation,laser power,atmospheric condition and surface quality of detector′s material are the main inputs of the fuzzy evaluation.The applicability of the fuzzy evaluation is verified by combing experimental and theoretical methods.
