Abstract:Miss distance is an important index in measuring the performance of guidance and control system. Based on the radio-laser combination fuze, a post-test miss distance estimation method is proposed by developing the relationships among the miss distance, activation distance, and miss distance direction. Both slide rail testing and flight testing demonstrate the high accuracy of the proposed miss distance estimation method. Furthermore, the universality of the proposed estimation method makes it possible to be used for a post-test estimation of miss distance with similar mechanism.
