Target threat assessment method based on cloud model and entropy weight

The accuracy in real-time of target threat assessment have great significance to UAV air combat. The target threat assessment method based on cloud model and entropy weight was proposed. According to characteristics of the UAV air combat, the threat assessment index system was established, the cloud model transformation was carried out for different evaluation indexes, and entropy weight was used to give each index a reasonable weight. Finally, the threat level was carried out. The example showed that: this method can effectively avoid man-made determine the weight of each index of the threat of subjectivity in the traditional method, and the effective treatment of qualitative indicators to improve evaluation accuracy, an new method for the UAV air threat assessment is provided.
