Abstract:

Aiming at the threat assessment of targets in air defense combats, we propose a new target assessment method
based on improved grey correlation algorithm. Time sequence weights are introduced to construct the dynamic
threat assessment model of targets, which improves traditional methods by on-ly assessing current targets’
threat. According to subjective and objective properties, the weights of tar-gets threat elements are
calculated in real time, which are then converted to the same layer by using the set pair analysis theory.
Finally, the improved grey correlation algorithm based on the technique for or-der preference by similarity
to an ideal solution (TOPSIS) is applied to get the final targets threat order. Theoretical analysis and
simulation results prove the reliability and validity of the method.

Key words: threat assessment, grey correlation algorithm, TOPSIS, combinatorial weighting method
