Statistical testing data generation for UAS

The reliability of UAS(Unmanned Aircraft Systems) is of vital importance in practical applications. The most effective method to guarantee the reliability of UAS is to test UAS with multiple types of testing data. In this paper, we propose a method for the testing data generation of UAS in consideration of the combination and weight of the input data, which improves the availability of the method in UAS. Then we make four experiments to verify the effectiveness of the proposed method: (1) the random testing data generation experiment; (2) testing data generation considering the combination of input data experiment; (3) testing data generation considering the combination and weight of input data experiment; (4) the history data from the actual usage situation. Experiments results show that the method proposed in this paper is closer to the reality. At last, we analyse the code coverage by using Code Test System(CTS). And the analysis reflects that the proposed method has a better coverage than other methods.
