Abstract
The purpose of this study was to analyze the effect of the accuracy of the reception on the result of attack. We classified the pattern of reception in four clusters by k-means clustering. And four clusters were named "A" type, "A-B" type, "B" type and "C" type.
We compared the attack performance of these four clusters. Results indicated that "C" type’s kill ratio was lower than other clusters. And "C" type’s and "B" type’s miss ratio was higher than "A" type and "A-B" type. In addition, there were no significant diｆｆerences between "A" type and "A-B" type. These results indicated that the accuracy of reception, especially A pass ratio, does not have positive effect for the result of attack.
