Study of helicopter-borne guided missiles' impact accuracy assessment

An assessment method of guided weapon's impact accuracy was proposed. It is proven by flight-test that the expectation and variance results obtained from large-sample simulation model could be used as acceptance standard of small-sample test. Two kinds of helicopter-borne aiming error analysis methods, i.e. approximating constant error analysis method and random error analysis method, with respect to different cases were discussed. The assessment standard of illumination accuracy of aiming systems was proposed.
