To evaluate the hitting accuracy of hypersonic vehicles scientifically and reasonably, this paper proposes a high accuracy evaluation method using the error spectrum. First, the hit accuracy data of hypersonic vehicles are preprocessed to obtain the relative distance error. Secondly, the root mean square, average Euclidean error, harmonic average error, median error, error mode metric, geometric average error and iterative mid-range error are constructed to reflect the hitting accuracy of hypersonic vehicles. Then, we build the high accuracy evaluation model and its credibility model for hypersonic vehicles. Finally, two examples are given to verify the correctness and rationality of the proposed method. The simulation results show that this method can obtain not only the result of the hit accuracy evaluation, but also the credibility of the result. This research provides a new scientific evaluation method for evaluating high hitting accuracy of hypersonic vehicles.
