Judging air-raid attack targets is a complicated system project which includes a large amount of different dimension factors. The traditional manpower qualitative judging mode hasn′t applied to information-based air-defense operation any more. To solve the above-mentioned problem, in view of the demand of choosing important shelter targets during the commanding of aerial defense operation, the effect factors in choosing the air-raid attack by the air-raid side are analyzed based on the theory of modern air-raid attack target and from the view of aerial defense force. Then, applying the grey fixed weight clustering theory, an air raid targets range model is set up by the combination of the qualitative and quantitative analyses. This model can be used to compose the center of campaign, then the pivot and order of the air raid targets can be estimated. The model can be applied to managing fire power and can be a reference frame to the air-defense force.
