| 摘 要： | 同一仪表的工具误差,对不同弹道的影响(如落点偏差)是不同的。本文避开传统的分离误差系数方法,而运用线性回归方法,依据试验弹道的遥、外测参数直接折合出仪表误差造成的正常弹道落点偏差,以提供对型号弹进行精度鉴定的可靠验前信息。在折合方法中利用AIC(Akaike Information Criterion)准则选择自变元及消去变换法实施运算。给出了对典型弹的数字仿真结果、数例说明该方法有较高的折合精度。

| Abstract: | The same instrument error effect on different trajectories is different. This paper adopts a linear regression method to caculate directly the normal trajectory impact error that caused by instrument error, according to the date from the remote and tracking measurement, while giving up the conventional error separation method. In this way, the reliable prior information is provided to evaluate the accuracy of a batch of missiles. In this method, Akaike Information Criterion (AIC) and the variable dissolution method are also use to operation for realization to select the candidate variables. The digital simulation result shows the high accuracy of this new approach. |
