| With the continuous development of infrared interference means, its more and more important to establish a set of scientific, reasonable and concise infrared anti-interference evaluation index system. Aimed at the problems that redundant phenomenon is in existence in infrared anti interference evaluation index system and there is lacking in rationality, firstly, the evaluation index system of infrared anti jamming is constructed from the inherent performance index, anti jamming performance index and missile tactical performance index, and then through the infrared anti-interference experiment simulation platform, set up corresponding disturbance variable is set up, huge amounts of data preprocessing are obtained. Next, the FP Growth algorithm in data mining is used to mine and analyze the anti interference experimental simulation data, and the association rules between disturbance variable and indexes are obtained. Finally, the index system is simplified through the strength of these association rules. As a result, the redundant items are removed for the index contracted and the core indexes are in existence. |
