基于综合序贯截尾法的捷联式导弹落点密集度检验

针对小子样试验中精度评定工作的需要,设计了一种弹道落点密集度的综合序贯截尾评定方法。首先,利用惯性坐标系内弹上惯性测量组合和弹载计算机共同完成导航计算任务的导航方程建立弹道仿真模型,求解弹道落点偏差;然后从评定结论置信度与所需试验子样数量之间的矛盾出发,设计了综合序贯截尾检验方法,讨论了最小发数的确定方法,论证了该方法应用于捷联式导弹落点密集度检验中的可行性。最后仿真实例验证了该方法的有效性。

Fall point dispersion of strapdown missile intensive test based on the integrated sequential truncation method

Address the needs of the accuracy of the assessment work in small sample experiments, designed the evaluation method of a ballistic impact point intensive Sequential Truncation. Firstly, under the inertial coordinate system, established the ballistic simulation model used the missile inertial measurement unit and the onboard computer together to solve the ballistic impact point deviation. Then, starting from the contradiction between the assessment conclusions confidence degree and the required experimental sub-sample number, established an integrated sequential truncation method, discussed a minimum number determine method, the feasibility of the method used in fall point dispersion of strapdown missile intensive test. Finally the simulation is made which verify the effectiveness of the proposed approach. Key words: trajectory simulation; fall point dispersion; integrated sequential censored assessment; minimum testing number.
